Dividing by a tricky number? Break the divisor into two smaller factors and divide by each in turn. ÷6 becomes ÷2 then ÷3; ÷12 becomes ÷3 then ÷4. Two easy divisions beat one hard one.
Watch the method
96 ÷ 6: since 6 = 2 × 3, divide by 2 (96 → 48), then by 3 (48 → 16). Two small steps you already know.
6 is 2 × 3, so divide by 2 first.
Then divide by 3.
Your turn
Use the method, then check. Stuck? Reveal the steps.
Dividing by a product is the same as dividing by each factor one after another. ÷6 = ÷2 ÷3, ÷12 = ÷3 ÷4, ÷15 = ÷3 ÷5. Choose factors from your times tables.
Why it works
Sharing among 6 people = first split into 2 big groups, then each into 3.
84 ÷ 6
÷2
84 → 42.
÷3
42 → 14.
96 ÷ 6
÷2
96 → 48.
÷3
48 → 16.
180 ÷ 15
÷3
180 → 60.
÷5
60 → 12.
Adding the factors instead of using both as divisors.
÷6 is ÷2 THEN ÷3 — two divisions, not ÷5 (2+3).
Choosing factors that don't multiply to the divisor.
The two factors must multiply back to the divisor: 2 × 3 = 6, 3 × 4 = 12.
