\begin{array}{l}\phantom{20)}\phantom{1}\\20\overline{)35}\\\end{array}
Use the 1^{st} digit 3 from dividend 35
\begin{array}{l}\phantom{20)}0\phantom{2}\\20\overline{)35}\\\end{array}
Since 3 is less than 20, use the next digit 5 from dividend 35 and add 0 to the quotient
\begin{array}{l}\phantom{20)}0\phantom{3}\\20\overline{)35}\\\end{array}
Use the 2^{nd} digit 5 from dividend 35
\begin{array}{l}\phantom{20)}01\phantom{4}\\20\overline{)35}\\\phantom{20)}\underline{\phantom{}20\phantom{}}\\\phantom{20)}15\\\end{array}
Find closest multiple of 20 to 35. We see that 1 \times 20 = 20 is the nearest. Now subtract 20 from 35 to get reminder 15. Add 1 to quotient.
\text{Quotient: }1 \text{Reminder: }15
Since 15 is less than 20, stop the division. The reminder is 15. The topmost line 01 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.
