\begin{array}{l}\phantom{18)}\phantom{1}\\18\overline{)882}\\\end{array}
Use the 1^{st} digit 8 from dividend 882
\begin{array}{l}\phantom{18)}0\phantom{2}\\18\overline{)882}\\\end{array}
Since 8 is less than 18, use the next digit 8 from dividend 882 and add 0 to the quotient
\begin{array}{l}\phantom{18)}0\phantom{3}\\18\overline{)882}\\\end{array}
Use the 2^{nd} digit 8 from dividend 882
\begin{array}{l}\phantom{18)}04\phantom{4}\\18\overline{)882}\\\phantom{18)}\underline{\phantom{}72\phantom{9}}\\\phantom{18)}16\\\end{array}
Find closest multiple of 18 to 88. We see that 4 \times 18 = 72 is the nearest. Now subtract 72 from 88 to get reminder 16. Add 4 to quotient.
\begin{array}{l}\phantom{18)}04\phantom{5}\\18\overline{)882}\\\phantom{18)}\underline{\phantom{}72\phantom{9}}\\\phantom{18)}162\\\end{array}
Use the 3^{rd} digit 2 from dividend 882
\begin{array}{l}\phantom{18)}049\phantom{6}\\18\overline{)882}\\\phantom{18)}\underline{\phantom{}72\phantom{9}}\\\phantom{18)}162\\\phantom{18)}\underline{\phantom{}162\phantom{}}\\\phantom{18)999}0\\\end{array}
Find closest multiple of 18 to 162. We see that 9 \times 18 = 162 is the nearest. Now subtract 162 from 162 to get reminder 0. Add 9 to quotient.
\text{Quotient: }49 \text{Reminder: }0
Since 0 is less than 18, stop the division. The reminder is 0. The topmost line 049 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 49.
