## What Is Long Division?

Long division is a method for dividing numbers.Long division is used for dividing numbers that have many digits.

## A Real Example of How to Do Long Division

Doing long division is easy.## Question

Divide the numbers below.## Step-by-Step:

## 1

Identify the number being

*divided*(called the dividend) and the number you are*dividing by*(called the divisor).## 2

Write the dividend inside the

*long division bracket*and the divisor outside to its left:## 3

Divide the first digit of the dividend (1) by the divisor (6). Do not count remainders.

1 ÷ 6 = 0

6 goes into 1 **0**times.## 4

Write the answer (0) above the long division bracket.

## 5

Multiply the answer from

**Step 3**(0) with the divisor (6).
0 × 6 = 0

Write the answer underneath the digit divided into:
## 6

Subtract the bottom number (0) from the top number (1).

1 − 0 = 1

## 7

Bring down the next digit of the dividend (3).

## 8

Divide this number (13) by the divisor (6). Do not count remainders.

13 ÷ 6 = 2 ~~ r 1 ~~

6 goes into 13 **2**times.## 9

Write the answer (2) above the long division bracket.

## 10

Multiply the answer from

**Step 8**(2) with the divisor (6).
2 × 6 = 12

Write the answer underneath the number divided into:
## 11

Subtract the bottom number (12) from the top number (13).

13 − 12 = 1

## 12

Bring down the next digit of the dividend (8).

## 13

Divide this number (18) by the divisor (6). Do not count remainders.

18 ÷ 6 = 3

6 goes into 18 **3**times.## 14

Write the answer (3) above the long division bracket.

## 15

Multiply the answer from

**Step 13**(3) with the divisor (6).
3 × 6 = 18

Write the answer underneath the number divided into:
## 16

Subtract the bottom number (18) from the top number (18).

18 − 18 = 0

There are no more digits to bring down.
## Answer:

The solution to 138 ÷ 6 is 23.## Parts of a Division

- The number you divide into is the
**dividend**. - The number you divide
*by*is the**divisor**. - The result of the division is the
**quotient**.

## Short Cut for Long Division

When you gain enough confidence, you will notice that the first few steps in this lesson are not necessary. In**Step 3**of the example, 1 is divided by 6, and so won't divide at least once. That is why

**0**was written above. Instead, don't divide by the first digit of the dividend, but move along the digits, left to right, until you find the first number larger than the divisor. Just remember that the answer must be written above the last digit. The 2 must be written above the 3 in 13, not the 1.
