\begin{array}{l}\phantom{100)}\phantom{1}\\100\overline{)220}\\\end{array}
Use the 1^{st} digit 2 from dividend 220
\begin{array}{l}\phantom{100)}0\phantom{2}\\100\overline{)220}\\\end{array}
Since 2 is less than 100, use the next digit 2 from dividend 220 and add 0 to the quotient
\begin{array}{l}\phantom{100)}0\phantom{3}\\100\overline{)220}\\\end{array}
Use the 2^{nd} digit 2 from dividend 220
\begin{array}{l}\phantom{100)}00\phantom{4}\\100\overline{)220}\\\end{array}
Since 22 is less than 100, use the next digit 0 from dividend 220 and add 0 to the quotient
\begin{array}{l}\phantom{100)}00\phantom{5}\\100\overline{)220}\\\end{array}
Use the 3^{rd} digit 0 from dividend 220
\begin{array}{l}\phantom{100)}002\phantom{6}\\100\overline{)220}\\\phantom{100)}\underline{\phantom{}200\phantom{}}\\\phantom{100)9}20\\\end{array}
Find closest multiple of 100 to 220. We see that 2 \times 100 = 200 is the nearest. Now subtract 200 from 220 to get reminder 20. Add 2 to quotient.
\text{Quotient: }2 \text{Reminder: }20
Since 20 is less than 100, stop the division. The reminder is 20. The topmost line 002 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 2.
