At the end of this lesson, students should be able to do long division with ease.
Long divisionis a method of division. It helps you to divide numbers that you can’t easily divide.
64 ÷ 2
When doing long division, it is very important to start from the left, that is the number in the tens column.
Looking at the example above, the 2 (divisor) is used to divide the dividend which is the 64.
6 Tens ÷ 2 = 3 Tens
Write 3 in the Tens Column directly on the bar above the 6 on the left.
Multiply the quotient by the divisor, 2 x 3 Tens = 6 Tens
Write the product 6 under the 6 Tens.
Next subtract the product from the dividend in the tens column, 6 – 6 = 0
Now move to the number on the right, that is the number in the units column. Bring down the 4 units by drawing an arrow downwards to show where the number is placed. Repeat the process for the 4.
4 units ÷ 2 = 2 units
Write 2 in the units column.
2 x 2 = 4
Write 4 under 4 units, 4 – 4 = 0
∴ 64 ÷ 2 = 32
∴ 35 ÷ 3 = 11 remainder 2 because 2 cannot be divided by 3.
