Lesson details
Key learning points
- Long division records the subtraction as a calculation underneath the dividend.
- Long division records the regrouping alongside the subtraction.
- There are similarities and differences between long and short division.
Keywords
Estimate - Estimate means to find a value that is close enough to the right answer, usually with some thought or calculation involved.
Long division - Long division is a method used for dividing large numbers by breaking the number down into smaller groups.

Common misconception
Pupils may not unitise when using long division and make errors (e.g. when dividing 7 hundreds by 12).
Explain to pupils that they are looking for multiples of the divisor (1 hundred × 12 = 1,200). This becomes clearer when dividing the tens digits (6 tens × 12 = 72 tens).
