`5` goes into `7` once. So write `1` above the line.
Multiply `1` to `5` and write the answer below `7`
Subtract `5` from `7` and write the answer one line below
Since `5` cannot go into `2` anymore, `2` is left as the Remainder and `1` is the QuotientSubstitute values into the given formula$$\frac{\color{#007DDC}{b}}{\color{#9a00c7}{c}}$$ `=` $$\color{#00880A}{Q}\frac{\color{#e65021}{R}}{\color{#9a00c7}{c}}$$ $$\frac{\color{#007DDC}{7}}{\color{#9a00c7}{5}}$$ `=` $$\color{#00880A}{1}\frac{\color{#e65021}{2}}{\color{#9a00c7}{5}}$$ Tom used `1 2/5kg`.`1 2/5kg` of potatoes -
