In these lessons, we will look at some examples of the long division of whole numbers.
In division, the number called the dividend is divided by the divisor, and the result is called quotient.
The following diagrams show the parts of a division: dividend, divisor, quotient, remainder. Scroll down the page for more examples and solutions long division.
Step 1: Start on the left. Check if first digit, 5, is bigger than the divisor 12. Since 5 is not, we need to take the next digit as well.
51 divided by 12 gives 4 as the quotient since 12 × 4 = 48.
Write 4 above 1.
Step 2: Write the number 48 below 51. Subtract 48 from 51 to get a remainder of 3. Bring down the next digit, 6, and write it after 3.
Step 3: Now repeat from Step 1. 36 divided by 12, gives 3. Write 3 above 6. Write the number 36 below 36. Subtract 36 from 36 to get a remainder of 0.
Your answer is then 43.
Step 1: Start on the left. Check if first digit, 9, is bigger than the divisor 12. Since 9 is not, we need to take the next digit as well.
99 divided by 12 gives 8 as the quotient since 12 × 8 = 96.
Write 8 above 9.
Step 2: Write the number 96 below 99. Subtract 96 from 99 to
get a remainder of 3. Bring down the next digit, 3, and write it after 3.
Step 3: Now repeat from Step 1. 33 divided by 12, gives 2. Write 2 above 3. Write the number 24 below 33. Subtract 24 from 33 to get a remainder of 9.
Your answer is then 82 remainder 9.
TAKE NOTE: For division, the divisor cannot be 0. For example, 23 ÷ 0 is not permissible.
