## Introduction

Hello Challenger, welcome to our guide on how to do long division. Long division can be a challenging task, especially for younger students who are just learning math. However, learning how to do long division is an essential skill that will prove to be beneficial throughout your academic and personal life. In this guide, we will walk you through the process of how to do long division in a step-by-step manner. By the end of this guide, you will have a good understanding of how to perform long division with ease, confidence, and accuracy.

Long division is a fundamental concept in arithmetic that allows us to divide large numbers with the remainder. It is crucial to mastering elementary math and eventually moving on to more advanced math courses. By knowing how to perform long division, you will be able to solve complex math problems accurately and efficiently. So, without further ado, let’s start by understanding the basic concept of long division.

### What is long division?

In simple terms, long division is a method of dividing numbers. It is called “long” division because it involves multiple steps and requires dividing one digit at a time. When dividing a larger number by a smaller number, long division helps us determine how many times the smaller number goes into the bigger one and what the remainder is. The process involves dividing the dividend (the number being divided) by the divisor (the number we are dividing by) and finding the quotient (the answer) and the remainder (what is left over when the dividend is not divisible by the divisor).

To understand how long division works, consider the following example:

Dividend | 4 5 6 7 4 |
---|---|

Divisor | 3 |

The above table represents the division of 4,5674 by 3. The first step of long division is to divide the first digit of the dividend (4) by the divisor (3). As 3 does not go into 4, we divide the first two digits (45) by 3, which gives us 15. We then multiply 15 by 3, which gives us 45. We subtract 45 from 45, which gives us zero, and we bring down the next digit (6).

The process continues by dividing 36 by 3, which gives us 12. We multiply 12 by 3, which gives us 36. We subtract 36 from 36, which gives us zero, and we bring down the next digit (7). The process continues until we have divided all the digits of the dividend by the divisor.

Now that we have a basic understanding of long division, let’s dive into the step-by-step process of performing long division.

## Step-by-Step Guide of How to Do Long Division

### Step 1: Divide

The first step of long division is to divide the first digit of the dividend (the number being divided) by the divisor (the number we are dividing by). Write the answer (the quotient) on top of the division symbol.

For example, if we are dividing 4567 by 3, we would write:

1 | | | 4 5 6 7 | | | 3 |

### Step 2: Multiply

Multiply the quotient by the divisor, and write the answer below the dividend. The product is known as the partial product.

For our example, we multiply 1 by 3, which gives us 3.

| | 4 5 6 7 | | | 3 | |

– 3 |

### Step 3: Subtract

Subtract the partial product from the dividend, and write the remainder below the partial product.

In our example, we subtract 3 from 4, which gives us 1. We then bring down the next digit (5).

| | 4 5 6 7 | | | 3 | |

– 3 | ||||

1 5 |

### Step 4: Repeat

Repeat steps 2 and 3 until you have divided all the digits of the dividend by the divisor.

Continuing our example, we multiply the quotient (5) by the divisor (3), which gives us 15. We subtract 15 from 156, which gives us 1. We bring down the next digit (6) and repeat the process.

| | 4 5 6 7 | | | 3 | |

– 3 | ||||

1 5 | ||||

– 15 | ||||

1 6 |

The process continues until we have divided all the digits of the dividend by the divisor. In this case, the answer is 1522 with a remainder of 1.

## FAQs

### What if the answer has a decimal?

If the division results in a decimal number, you can use decimal long division. The process is the same as long division, but you include decimal points in the dividend and move them up to the answer.

### What if the divisor is larger than the dividend?

If the divisor is larger than the dividend, you cannot perform long division with this pair of numbers.

### What if the dividend has a zero in it?

If the dividend includes a zero, it must be included in long division. Ensure that you include it in the correct place when setting up your problem.

### What if the divisor is a fraction?

If the divisor is a fraction, you must first convert the division question to a multiplication question by writing the dividend as a fraction and using the reciprocal of the divisor. You can then use long division with the resulting fraction.

### Can I use long division to divide polynomials?

Yes, long division can be used to divide polynomials. The process is the same as it is for numbers, but you must keep track of the powers of the variables.

### How do I check my answer?

You can check your answer by multiplying the quotient and the divisor and adding the remainder. The result should be equal to the dividend.

### Are there any shortcuts I can use for long division?

Yes, there are a few shortcuts you can use, such as the “chunking” or “factoring” method. However, these shortcuts may not work for all problems, so it is essential to understand the traditional long division method.

### Conclusion

In conclusion, learning how to do long division is an essential mathematical skill that you will encounter throughout your academic and personal life. By using the step-by-step method mentioned in this guide, you will be able to perform long division efficiently and accurately. Remember, practice makes perfect, and the more you practice, the easier it will become.

So, go ahead, try it out for yourself, and soon you’ll be a long division whiz!
