\begin{array}{l}\phantom{22)}\phantom{1}\\22\overline{)55}\\\end{array}
Use the 1^{st} digit 5 from dividend 55
\begin{array}{l}\phantom{22)}0\phantom{2}\\22\overline{)55}\\\end{array}
Since 5 is less than 22, use the next digit 5 from dividend 55 and add 0 to the quotient
\begin{array}{l}\phantom{22)}0\phantom{3}\\22\overline{)55}\\\end{array}
Use the 2^{nd} digit 5 from dividend 55
\begin{array}{l}\phantom{22)}02\phantom{4}\\22\overline{)55}\\\phantom{22)}\underline{\phantom{}44\phantom{}}\\\phantom{22)}11\\\end{array}
Find closest multiple of 22 to 55. We see that 2 \times 22 = 44 is the nearest. Now subtract 44 from 55 to get reminder 11. Add 2 to quotient.
\text{Quotient: }2 \text{Reminder: }11
Since 11 is less than 22, stop the division. The reminder is 11. The topmost line 02 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 2.
