\begin{array}{l}\phantom{18)}\phantom{1}\\18\overline{)1008}\\\end{array}
Use the 1^{st} digit 1 from dividend 1008
\begin{array}{l}\phantom{18)}0\phantom{2}\\18\overline{)1008}\\\end{array}
Since 1 is less than 18, use the next digit 0 from dividend 1008 and add 0 to the quotient
\begin{array}{l}\phantom{18)}0\phantom{3}\\18\overline{)1008}\\\end{array}
Use the 2^{nd} digit 0 from dividend 1008
\begin{array}{l}\phantom{18)}00\phantom{4}\\18\overline{)1008}\\\end{array}
Since 10 is less than 18, use the next digit 0 from dividend 1008 and add 0 to the quotient
\begin{array}{l}\phantom{18)}00\phantom{5}\\18\overline{)1008}\\\end{array}
Use the 3^{rd} digit 0 from dividend 1008
\begin{array}{l}\phantom{18)}005\phantom{6}\\18\overline{)1008}\\\phantom{18)}\underline{\phantom{9}90\phantom{9}}\\\phantom{18)9}10\\\end{array}
Find closest multiple of 18 to 100. We see that 5 \times 18 = 90 is the nearest. Now subtract 90 from 100 to get reminder 10. Add 5 to quotient.
\begin{array}{l}\phantom{18)}005\phantom{7}\\18\overline{)1008}\\\phantom{18)}\underline{\phantom{9}90\phantom{9}}\\\phantom{18)9}108\\\end{array}
Use the 4^{th} digit 8 from dividend 1008
\begin{array}{l}\phantom{18)}0056\phantom{8}\\18\overline{)1008}\\\phantom{18)}\underline{\phantom{9}90\phantom{9}}\\\phantom{18)9}108\\\phantom{18)}\underline{\phantom{9}108\phantom{}}\\\phantom{18)9999}0\\\end{array}
Find closest multiple of 18 to 108. We see that 6 \times 18 = 108 is the nearest. Now subtract 108 from 108 to get reminder 0. Add 6 to quotient.
\text{Quotient: }56 \text{Reminder: }0
Since 0 is less than 18, stop the division. The reminder is 0. The topmost line 0056 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 56.
