\begin{array}{l}\phantom{17)}\phantom{1}\\17\overline{)31}\\\end{array}
Use the 1^{st} digit 3 from dividend 31
\begin{array}{l}\phantom{17)}0\phantom{2}\\17\overline{)31}\\\end{array}
Since 3 is less than 17, use the next digit 1 from dividend 31 and add 0 to the quotient
\begin{array}{l}\phantom{17)}0\phantom{3}\\17\overline{)31}\\\end{array}
Use the 2^{nd} digit 1 from dividend 31
\begin{array}{l}\phantom{17)}01\phantom{4}\\17\overline{)31}\\\phantom{17)}\underline{\phantom{}17\phantom{}}\\\phantom{17)}14\\\end{array}
Find closest multiple of 17 to 31. We see that 1 \times 17 = 17 is the nearest. Now subtract 17 from 31 to get reminder 14. Add 1 to quotient.
\text{Quotient: }1 \text{Reminder: }14
Since 14 is less than 17, stop the division. The reminder is 14. The topmost line 01 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.
