\begin{array}{l}\phantom{20)}\phantom{1}\\20\overline{)53}\\\end{array}
Use the 1^{st} digit 5 from dividend 53
\begin{array}{l}\phantom{20)}0\phantom{2}\\20\overline{)53}\\\end{array}
Since 5 is less than 20, use the next digit 3 from dividend 53 and add 0 to the quotient
\begin{array}{l}\phantom{20)}0\phantom{3}\\20\overline{)53}\\\end{array}
Use the 2^{nd} digit 3 from dividend 53
\begin{array}{l}\phantom{20)}02\phantom{4}\\20\overline{)53}\\\phantom{20)}\underline{\phantom{}40\phantom{}}\\\phantom{20)}13\\\end{array}
Find closest multiple of 20 to 53. We see that 2 \times 20 = 40 is the nearest. Now subtract 40 from 53 to get reminder 13. Add 2 to quotient.
\text{Quotient: }2 \text{Reminder: }13
Since 13 is less than 20, stop the division. The reminder is 13. The topmost line 02 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 2.
