\begin{array}{l}\phantom{100)}\phantom{1}\\100\overline{)4239}\\\end{array}
Use the 1^{st} digit 4 from dividend 4239
\begin{array}{l}\phantom{100)}0\phantom{2}\\100\overline{)4239}\\\end{array}
Since 4 is less than 100, use the next digit 2 from dividend 4239 and add 0 to the quotient
\begin{array}{l}\phantom{100)}0\phantom{3}\\100\overline{)4239}\\\end{array}
Use the 2^{nd} digit 2 from dividend 4239
\begin{array}{l}\phantom{100)}00\phantom{4}\\100\overline{)4239}\\\end{array}
Since 42 is less than 100, use the next digit 3 from dividend 4239 and add 0 to the quotient
\begin{array}{l}\phantom{100)}00\phantom{5}\\100\overline{)4239}\\\end{array}
Use the 3^{rd} digit 3 from dividend 4239
\begin{array}{l}\phantom{100)}004\phantom{6}\\100\overline{)4239}\\\phantom{100)}\underline{\phantom{}400\phantom{9}}\\\phantom{100)9}23\\\end{array}
Find closest multiple of 100 to 423. We see that 4 \times 100 = 400 is the nearest. Now subtract 400 from 423 to get reminder 23. Add 4 to quotient.
\begin{array}{l}\phantom{100)}004\phantom{7}\\100\overline{)4239}\\\phantom{100)}\underline{\phantom{}400\phantom{9}}\\\phantom{100)9}239\\\end{array}
Use the 4^{th} digit 9 from dividend 4239
\begin{array}{l}\phantom{100)}0042\phantom{8}\\100\overline{)4239}\\\phantom{100)}\underline{\phantom{}400\phantom{9}}\\\phantom{100)9}239\\\phantom{100)}\underline{\phantom{9}200\phantom{}}\\\phantom{100)99}39\\\end{array}
Find closest multiple of 100 to 239. We see that 2 \times 100 = 200 is the nearest. Now subtract 200 from 239 to get reminder 39. Add 2 to quotient.
\text{Quotient: }42 \text{Reminder: }39
Since 39 is less than 100, stop the division. The reminder is 39. The topmost line 0042 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 42.
