\begin{array}{l}\phantom{22)}\phantom{1}\\22\overline{)77}\\\end{array}
Use the 1^{st} digit 7 from dividend 77
\begin{array}{l}\phantom{22)}0\phantom{2}\\22\overline{)77}\\\end{array}
Since 7 is less than 22, use the next digit 7 from dividend 77 and add 0 to the quotient
\begin{array}{l}\phantom{22)}0\phantom{3}\\22\overline{)77}\\\end{array}
Use the 2^{nd} digit 7 from dividend 77
\begin{array}{l}\phantom{22)}03\phantom{4}\\22\overline{)77}\\\phantom{22)}\underline{\phantom{}66\phantom{}}\\\phantom{22)}11\\\end{array}
Find closest multiple of 22 to 77. We see that 3 \times 22 = 66 is the nearest. Now subtract 66 from 77 to get reminder 11. Add 3 to quotient.
\text{Quotient: }3 \text{Reminder: }11
Since 11 is less than 22, stop the division. The reminder is 11. The topmost line 03 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 3.
