\begin{array}{l}\phantom{17)}\phantom{1}\\17\overline{)81}\\\end{array}
Use the 1^{st} digit 8 from dividend 81
\begin{array}{l}\phantom{17)}0\phantom{2}\\17\overline{)81}\\\end{array}
Since 8 is less than 17, use the next digit 1 from dividend 81 and add 0 to the quotient
\begin{array}{l}\phantom{17)}0\phantom{3}\\17\overline{)81}\\\end{array}
Use the 2^{nd} digit 1 from dividend 81
\begin{array}{l}\phantom{17)}04\phantom{4}\\17\overline{)81}\\\phantom{17)}\underline{\phantom{}68\phantom{}}\\\phantom{17)}13\\\end{array}
Find closest multiple of 17 to 81. We see that 4 \times 17 = 68 is the nearest. Now subtract 68 from 81 to get reminder 13. Add 4 to quotient.
\text{Quotient: }4 \text{Reminder: }13
Since 13 is less than 17, stop the division. The reminder is 13. The topmost line 04 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 4.
