\begin{array}{l}\phantom{12)}\phantom{1}\\12\overline{)756}\\\end{array}
Use the 1^{st} digit 7 from dividend 756
\begin{array}{l}\phantom{12)}0\phantom{2}\\12\overline{)756}\\\end{array}
Since 7 is less than 12, use the next digit 5 from dividend 756 and add 0 to the quotient
\begin{array}{l}\phantom{12)}0\phantom{3}\\12\overline{)756}\\\end{array}
Use the 2^{nd} digit 5 from dividend 756
\begin{array}{l}\phantom{12)}06\phantom{4}\\12\overline{)756}\\\phantom{12)}\underline{\phantom{}72\phantom{9}}\\\phantom{12)9}3\\\end{array}
Find closest multiple of 12 to 75. We see that 6 \times 12 = 72 is the nearest. Now subtract 72 from 75 to get reminder 3. Add 6 to quotient.
\begin{array}{l}\phantom{12)}06\phantom{5}\\12\overline{)756}\\\phantom{12)}\underline{\phantom{}72\phantom{9}}\\\phantom{12)9}36\\\end{array}
Use the 3^{rd} digit 6 from dividend 756
\begin{array}{l}\phantom{12)}063\phantom{6}\\12\overline{)756}\\\phantom{12)}\underline{\phantom{}72\phantom{9}}\\\phantom{12)9}36\\\phantom{12)}\underline{\phantom{9}36\phantom{}}\\\phantom{12)999}0\\\end{array}
Find closest multiple of 12 to 36. We see that 3 \times 12 = 36 is the nearest. Now subtract 36 from 36 to get reminder 0. Add 3 to quotient.
\text{Quotient: }63 \text{Reminder: }0
Since 0 is less than 12, stop the division. The reminder is 0. The topmost line 063 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 63.
