$$\begin{array}{r}1?\\\\7\\overline{)91}\\\\-7\\\\\\hline21\\end{array}$$

Explanation:

Step1: Divide 21 by 7

We know that \( 7\times3 = 21 \), so we check how many times 7 can be multiplied to get as close to 21 as possible.

Step2: Find the remainder

Since \( 7\times3=21 \), when we divide 21 by 7, we have \( 21\div7 = 3 \) with a remainder of \( 21 - 7\times3=21 - 21 = 0 \).

Answer:

3 times, with a remainder of 0
