\begin{array}{l}\phantom{36)}\phantom{1}\\36\overline{)84}\\\end{array}
Use the 1^{st} digit 8 from dividend 84
\begin{array}{l}\phantom{36)}0\phantom{2}\\36\overline{)84}\\\end{array}
Since 8 is less than 36, use the next digit 4 from dividend 84 and add 0 to the quotient
\begin{array}{l}\phantom{36)}0\phantom{3}\\36\overline{)84}\\\end{array}
Use the 2^{nd} digit 4 from dividend 84
\begin{array}{l}\phantom{36)}02\phantom{4}\\36\overline{)84}\\\phantom{36)}\underline{\phantom{}72\phantom{}}\\\phantom{36)}12\\\end{array}
Find closest multiple of 36 to 84. We see that 2 \times 36 = 72 is the nearest. Now subtract 72 from 84 to get reminder 12. Add 2 to quotient.
\text{Quotient: }2 \text{Reminder: }12
Since 12 is less than 36, stop the division. The reminder is 12. The topmost line 02 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 2.
