Short division

Split the number into parts the divisor goes into easily. Divide each part, then add the answers. 158 ÷ 4 → 158 = 120 + 38. 120 ÷ 4 = 30, and 38 ÷ 4 = 9 remainder 2. 30 + 9 = 39, so the quotient is 39 and the remainder is 2. We write this as 158 ÷ 4 = 39 … 2. Check by multiplying: 4 × 39 = 156, 156 + 2 = 158. Another way is written division, starting from the highest place. The 1 in the hundreds is too small for 4, so take 15. 15 ÷ 4 is 3 remainder 3. Bring down the 8 to make 38, and 38 ÷ 4 is 9 remainder 2. When a place is too small to divide, the quotient gets a 0 there: 612 ÷ 3 = 204. Each question tells you whether it wants the quotient or the remainder. If it divides exactly, it wants the quotient.
