Dividing · Grade 4

In Grade 4 you learn: dividing by a 1-digit number with remainders and remainders in word problems.

Dividing shares a number into equal groups, or finds how many equal groups fit. For bigger numbers we use short division, and what to do with a remainder depends on the question.

Key facts

• Dividing shares a number into equal groups, or finds how many groups fit: 12 ÷ 3 = 4.
• Use the times tables backwards: 56 ÷ 8 = 7 because 7 × 8 = 56.
• To divide a 2-digit number, split it into parts the divisor goes into: 72 ÷ 3 = 60 ÷ 3 + 12 ÷ 3 = 24.
• Short division: divide each digit from the left, carrying the remainder to the next digit.
• Remainders: round up when everything must fit (buses, boxes); round down when only whole ones count (pieces, packs).
• Check a division by multiplying back: quotient × divisor + remainder = number.
