\begin{array}{l}\phantom{81)}\phantom{1}\\81\overline{)2260}\\\end{array}
Use the 1^{st} digit 2 from dividend 2260
\begin{array}{l}\phantom{81)}0\phantom{2}\\81\overline{)2260}\\\end{array}
Since 2 is less than 81, use the next digit 2 from dividend 2260 and add 0 to the quotient
\begin{array}{l}\phantom{81)}0\phantom{3}\\81\overline{)2260}\\\end{array}
Use the 2^{nd} digit 2 from dividend 2260
\begin{array}{l}\phantom{81)}00\phantom{4}\\81\overline{)2260}\\\end{array}
Since 22 is less than 81, use the next digit 6 from dividend 2260 and add 0 to the quotient
\begin{array}{l}\phantom{81)}00\phantom{5}\\81\overline{)2260}\\\end{array}
Use the 3^{rd} digit 6 from dividend 2260
\begin{array}{l}\phantom{81)}002\phantom{6}\\81\overline{)2260}\\\phantom{81)}\underline{\phantom{}162\phantom{9}}\\\phantom{81)9}64\\\end{array}
Find closest multiple of 81 to 226. We see that 2 \times 81 = 162 is the nearest. Now subtract 162 from 226 to get reminder 64. Add 2 to quotient.
\begin{array}{l}\phantom{81)}002\phantom{7}\\81\overline{)2260}\\\phantom{81)}\underline{\phantom{}162\phantom{9}}\\\phantom{81)9}640\\\end{array}
Use the 4^{th} digit 0 from dividend 2260
\begin{array}{l}\phantom{81)}0027\phantom{8}\\81\overline{)2260}\\\phantom{81)}\underline{\phantom{}162\phantom{9}}\\\phantom{81)9}640\\\phantom{81)}\underline{\phantom{9}567\phantom{}}\\\phantom{81)99}73\\\end{array}
Find closest multiple of 81 to 640. We see that 7 \times 81 = 567 is the nearest. Now subtract 567 from 640 to get reminder 73. Add 7 to quotient.
\text{Quotient: }27 \text{Reminder: }73
Since 73 is less than 81, stop the division. The reminder is 73. The topmost line 0027 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 27.
