\begin{array}{l}\phantom{13)}\phantom{1}\\13\overline{)78}\\\end{array}
Use the 1^{st} digit 7 from dividend 78
\begin{array}{l}\phantom{13)}0\phantom{2}\\13\overline{)78}\\\end{array}
Since 7 is less than 13, use the next digit 8 from dividend 78 and add 0 to the quotient
\begin{array}{l}\phantom{13)}0\phantom{3}\\13\overline{)78}\\\end{array}
Use the 2^{nd} digit 8 from dividend 78
\begin{array}{l}\phantom{13)}06\phantom{4}\\13\overline{)78}\\\phantom{13)}\underline{\phantom{}78\phantom{}}\\\phantom{13)99}0\\\end{array}
Find closest multiple of 13 to 78. We see that 6 \times 13 = 78 is the nearest. Now subtract 78 from 78 to get reminder 0. Add 6 to quotient.
\text{Quotient: }6 \text{Reminder: }0
Since 0 is less than 13, stop the division. The reminder is 0. The topmost line 06 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 6.
