To divide by 2, just halve the number!
Example: 24 ÷ 2 = 12 (half of 24)
To divide by 5, multiply by 2 and then divide by 10.
Example: 45 ÷ 5 = (45 × 2) ÷ 10 = 90 ÷ 10 = 9
To divide by 9, add the digits of the number. If the sum is more than 9, keep adding the digits until you get a single digit.
Example: 81 ÷ 9 = 9 (8 + 1 = 9)
729 ÷ 9 = 81 (7 + 2 + 9 = 18, 1 + 8 = 9)
Move the decimal point to the left by the number of zeros.
Example: 3500 ÷ 100 = 35 (move decimal 2 places left)
