A worked example
What is the result of 3 ) 85 ‾ 3\,\overline{\smash{\big)}\,85}\, 3 ) 85 ?
We need to find 3 ) 85 ‾ 3\,\overline{\smash{\big)}\,85}\, 3 ) 85 . Here 85 \; is the dividend and 3 \; is the divisor. The answer will have a quotient and a remainder.
3 ) ‾ 28 3 ) 85 ‾ 6 5 ‾ 25 24 ‾ 1 \begin{array}{r} \phantom{3\,\overline{\smash{\big)}\,}}28 \\ 3\,\overline{\smash{\big)}\,85} \\ \underline{6\phantom{5}} \\ 25 \\ \underline{24} \\ 1 \end{array} \\ 3 ) 28 3 ) 85 6 5 25 24 1 3 goes into 8, 2 times → 3 × 2 = 6 \to 3 \times 2 = 6 → 3 × 2 = 6 . Subtract → 8 − 6 = 2 \to 8 - 6 = 2 → 8 − 6 = 2 . Bring down to get 25 \\ 3 goes into 25, 8 times → 3 × 8 = 24 \to 3 \times 8 = 24 → 3 × 8 = 24 . Subtract → 25 − 24 = 1 \to 25 - 24 = 1 → 25 − 24 = 1 . The remainder is 1
The quotient is 28 \; with a remainder of 1 \, .
Check: 28 × \; \times \; × 3 + \; + \; + 1 = \; = \; = 84 + \; + \; + 1 = \; = \; = 85 ✓ \; \checkmark ✓

Your child learns the long-division algorithm with two- and three-digit numbers, with and without remainders, handles zeros appearing in the quotient, finds missing dividends and divisors, checks every answer by multiplying back, and applies long division to sharing and grouping word problems.
The long-division algorithm: 2-digit and 3-digit dividends with and without remainders in input and multiple-choice form, zeros in the quotient including identifying and counting which divisions produce one, missing dividends and divisors with and without remainders, division by powers and multiples of ten with remainders including remainder-only and quotient-and-remainder responses, checking long division by multiplication in both directions, and equal-sharing and grouping word problems with and without remainders.
