\begin{array}{l}\phantom{21)}\phantom{1}\\21\overline{)35}\\\end{array}
Use the 1^{st} digit 3 from dividend 35
\begin{array}{l}\phantom{21)}0\phantom{2}\\21\overline{)35}\\\end{array}
Since 3 is less than 21, use the next digit 5 from dividend 35 and add 0 to the quotient
\begin{array}{l}\phantom{21)}0\phantom{3}\\21\overline{)35}\\\end{array}
Use the 2^{nd} digit 5 from dividend 35
\begin{array}{l}\phantom{21)}01\phantom{4}\\21\overline{)35}\\\phantom{21)}\underline{\phantom{}21\phantom{}}\\\phantom{21)}14\\\end{array}
Find closest multiple of 21 to 35. We see that 1 \times 21 = 21 is the nearest. Now subtract 21 from 35 to get reminder 14. Add 1 to quotient.
\text{Quotient: }1 \text{Reminder: }14
Since 14 is less than 21, 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.
