# Division

Division using larger numbers can be written down using long division.

If you have memorised some division and multiplication tables, you can use them to divide in your head. Here are some examples of how you might solve problems:

• 42 ÷ 7

You could recall the 7 times table and remember that 7 x 6 = 42 to get the answer 6.

• 47 ÷ 9

You could recall that 45 ÷ 9 = 5 and count on from 45 to 47 to get the answer 5 remainder 2.

• 600 ÷ 8

Because 8 = 2 x 2 x 2, you could divide 600 by 2 and then divide by 2 again, and then divide by 2 again.

600 ÷ 2 = 300
300 ÷ 2 = 150
150 ÷ 2 = 75

• 67 ÷ 10 and 4.3 ÷ 10

To divide a number by 10, move the digits one place to the right, adding a zero if necessary.

67 ÷ 10 = 6.7
4.3 ÷ 10 = 0.43

• 290 ÷ 100 and 4.3 ÷ 100

To divide a number by 100, move the digits two places to the right, adding zeros if necessary.

290 ÷ 100 = 2.9
4.3 ÷ 100 = 0.043

• 24 ÷ 20

To divide by numbers such as 20, divide by the 2 first and then by the 10.

24 ÷ 2 = 12
12 ÷ 10 = 1.2
