\begin{array}{l}\phantom{36)}\phantom{1}\\36\overline{)72}\\\end{array}
Use the 1^{st} digit 7 from dividend 72
\begin{array}{l}\phantom{36)}0\phantom{2}\\36\overline{)72}\\\end{array}
Since 7 is less than 36, use the next digit 2 from dividend 72 and add 0 to the quotient
\begin{array}{l}\phantom{36)}0\phantom{3}\\36\overline{)72}\\\end{array}
Use the 2^{nd} digit 2 from dividend 72
\begin{array}{l}\phantom{36)}02\phantom{4}\\36\overline{)72}\\\phantom{36)}\underline{\phantom{}72\phantom{}}\\\phantom{36)99}0\\\end{array}
Find closest multiple of 36 to 72. We see that 2 \times 36 = 72 is the nearest. Now subtract 72 from 72 to get reminder 0. Add 2 to quotient.
\text{Quotient: }2 \text{Reminder: }0
Since 0 is less than 36, stop the division. The reminder is 0. The topmost line 02 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 2.
