\begin{array}{l}\phantom{12)}\phantom{1}\\12\overline{)83}\\\end{array}
Use the 1^{st} digit 8 from dividend 83
\begin{array}{l}\phantom{12)}0\phantom{2}\\12\overline{)83}\\\end{array}
Since 8 is less than 12, use the next digit 3 from dividend 83 and add 0 to the quotient
\begin{array}{l}\phantom{12)}0\phantom{3}\\12\overline{)83}\\\end{array}
Use the 2^{nd} digit 3 from dividend 83
\begin{array}{l}\phantom{12)}06\phantom{4}\\12\overline{)83}\\\phantom{12)}\underline{\phantom{}72\phantom{}}\\\phantom{12)}11\\\end{array}
Find closest multiple of 12 to 83. We see that 6 \times 12 = 72 is the nearest. Now subtract 72 from 83 to get reminder 11. Add 6 to quotient.
\text{Quotient: }6 \text{Reminder: }11
Since 11 is less than 12, stop the division. The reminder is 11. The topmost line 06 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 6.
