Halving Division
If you're dividing by 2, 4, 8, or 16, just keep halving. Divide in half twice for 4, three times for 8, and so on.
48 ÷ 8
8 is 2 three times
48 → 24 → 12 → 6
64 ÷ 16
16 is 2 four times
64 → 32 → 16 → 8 → 4
96 ÷ 4
4 is 2 two times
96 → 48 → 24
This is trick is the exact opposite of the doubling multiplication trick.
