\begin{array}{l}\phantom{80)}\phantom{1}\\80\overline{)1599}\\\end{array}
Use the 1^{st} digit 1 from dividend 1599
\begin{array}{l}\phantom{80)}0\phantom{2}\\80\overline{)1599}\\\end{array}
Since 1 is less than 80, use the next digit 5 from dividend 1599 and add 0 to the quotient
\begin{array}{l}\phantom{80)}0\phantom{3}\\80\overline{)1599}\\\end{array}
Use the 2^{nd} digit 5 from dividend 1599
\begin{array}{l}\phantom{80)}00\phantom{4}\\80\overline{)1599}\\\end{array}
Since 15 is less than 80, use the next digit 9 from dividend 1599 and add 0 to the quotient
\begin{array}{l}\phantom{80)}00\phantom{5}\\80\overline{)1599}\\\end{array}
Use the 3^{rd} digit 9 from dividend 1599
\begin{array}{l}\phantom{80)}001\phantom{6}\\80\overline{)1599}\\\phantom{80)}\underline{\phantom{9}80\phantom{9}}\\\phantom{80)9}79\\\end{array}
Find closest multiple of 80 to 159. We see that 1 \times 80 = 80 is the nearest. Now subtract 80 from 159 to get reminder 79. Add 1 to quotient.
\begin{array}{l}\phantom{80)}001\phantom{7}\\80\overline{)1599}\\\phantom{80)}\underline{\phantom{9}80\phantom{9}}\\\phantom{80)9}799\\\end{array}
Use the 4^{th} digit 9 from dividend 1599
\begin{array}{l}\phantom{80)}0019\phantom{8}\\80\overline{)1599}\\\phantom{80)}\underline{\phantom{9}80\phantom{9}}\\\phantom{80)9}799\\\phantom{80)}\underline{\phantom{9}720\phantom{}}\\\phantom{80)99}79\\\end{array}
Find closest multiple of 80 to 799. We see that 9 \times 80 = 720 is the nearest. Now subtract 720 from 799 to get reminder 79. Add 9 to quotient.
\text{Quotient: }19 \text{Reminder: }79
Since 79 is less than 80, stop the division. The reminder is 79. The topmost line 0019 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 19.
