If using short division to divide by a 2-digit number, pupils may be unsure how to record a 2-digit remainder. They may write one of the digits in the correct place and write the other either in the answer line or after the next digit, as shown for the remainder 10 in the examples below.

When the second digit is a zero, as here, they may even miss it out entirely!

Pupils need reassuring that a remainder can be more then one digit and that the whole remainder is written before the next digit in the usual way.
