\begin{array}{l}\phantom{21)}\phantom{1}\\21\overline{)65475}\\\end{array}
Use the 1^{st} digit 6 from dividend 65475
\begin{array}{l}\phantom{21)}0\phantom{2}\\21\overline{)65475}\\\end{array}
Since 6 is less than 21, use the next digit 5 from dividend 65475 and add 0 to the quotient
\begin{array}{l}\phantom{21)}0\phantom{3}\\21\overline{)65475}\\\end{array}
Use the 2^{nd} digit 5 from dividend 65475
\begin{array}{l}\phantom{21)}03\phantom{4}\\21\overline{)65475}\\\phantom{21)}\underline{\phantom{}63\phantom{999}}\\\phantom{21)9}2\\\end{array}
Find closest multiple of 21 to 65. We see that 3 \times 21 = 63 is the nearest. Now subtract 63 from 65 to get reminder 2. Add 3 to quotient.
\begin{array}{l}\phantom{21)}03\phantom{5}\\21\overline{)65475}\\\phantom{21)}\underline{\phantom{}63\phantom{999}}\\\phantom{21)9}24\\\end{array}
Use the 3^{rd} digit 4 from dividend 65475
\begin{array}{l}\phantom{21)}031\phantom{6}\\21\overline{)65475}\\\phantom{21)}\underline{\phantom{}63\phantom{999}}\\\phantom{21)9}24\\\phantom{21)}\underline{\phantom{9}21\phantom{99}}\\\phantom{21)99}3\\\end{array}
Find closest multiple of 21 to 24. We see that 1 \times 21 = 21 is the nearest. Now subtract 21 from 24 to get reminder 3. Add 1 to quotient.
\begin{array}{l}\phantom{21)}031\phantom{7}\\21\overline{)65475}\\\phantom{21)}\underline{\phantom{}63\phantom{999}}\\\phantom{21)9}24\\\phantom{21)}\underline{\phantom{9}21\phantom{99}}\\\phantom{21)99}37\\\end{array}
Use the 4^{th} digit 7 from dividend 65475
\begin{array}{l}\phantom{21)}0311\phantom{8}\\21\overline{)65475}\\\phantom{21)}\underline{\phantom{}63\phantom{999}}\\\phantom{21)9}24\\\phantom{21)}\underline{\phantom{9}21\phantom{99}}\\\phantom{21)99}37\\\phantom{21)}\underline{\phantom{99}21\phantom{9}}\\\phantom{21)99}16\\\end{array}
Find closest multiple of 21 to 37. We see that 1 \times 21 = 21 is the nearest. Now subtract 21 from 37 to get reminder 16. Add 1 to quotient.
\begin{array}{l}\phantom{21)}0311\phantom{9}\\21\overline{)65475}\\\phantom{21)}\underline{\phantom{}63\phantom{999}}\\\phantom{21)9}24\\\phantom{21)}\underline{\phantom{9}21\phantom{99}}\\\phantom{21)99}37\\\phantom{21)}\underline{\phantom{99}21\phantom{9}}\\\phantom{21)99}165\\\end{array}
Use the 5^{th} digit 5 from dividend 65475
\begin{array}{l}\phantom{21)}03117\phantom{10}\\21\overline{)65475}\\\phantom{21)}\underline{\phantom{}63\phantom{999}}\\\phantom{21)9}24\\\phantom{21)}\underline{\phantom{9}21\phantom{99}}\\\phantom{21)99}37\\\phantom{21)}\underline{\phantom{99}21\phantom{9}}\\\phantom{21)99}165\\\phantom{21)}\underline{\phantom{99}147\phantom{}}\\\phantom{21)999}18\\\end{array}
Find closest multiple of 21 to 165. We see that 7 \times 21 = 147 is the nearest. Now subtract 147 from 165 to get reminder 18. Add 7 to quotient.
\text{Quotient: }3117 \text{Reminder: }18
Since 18 is less than 21, stop the division. The reminder is 18. The topmost line 03117 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 3117.
