\begin{array}{l}\phantom{19)}\phantom{1}\\19\overline{)4100}\\\end{array}
Use the 1^{st} digit 4 from dividend 4100
\begin{array}{l}\phantom{19)}0\phantom{2}\\19\overline{)4100}\\\end{array}
Since 4 is less than 19, use the next digit 1 from dividend 4100 and add 0 to the quotient
\begin{array}{l}\phantom{19)}0\phantom{3}\\19\overline{)4100}\\\end{array}
Use the 2^{nd} digit 1 from dividend 4100
\begin{array}{l}\phantom{19)}02\phantom{4}\\19\overline{)4100}\\\phantom{19)}\underline{\phantom{}38\phantom{99}}\\\phantom{19)9}3\\\end{array}
Find closest multiple of 19 to 41. We see that 2 \times 19 = 38 is the nearest. Now subtract 38 from 41 to get reminder 3. Add 2 to quotient.
\begin{array}{l}\phantom{19)}02\phantom{5}\\19\overline{)4100}\\\phantom{19)}\underline{\phantom{}38\phantom{99}}\\\phantom{19)9}30\\\end{array}
Use the 3^{rd} digit 0 from dividend 4100
\begin{array}{l}\phantom{19)}021\phantom{6}\\19\overline{)4100}\\\phantom{19)}\underline{\phantom{}38\phantom{99}}\\\phantom{19)9}30\\\phantom{19)}\underline{\phantom{9}19\phantom{9}}\\\phantom{19)9}11\\\end{array}
Find closest multiple of 19 to 30. We see that 1 \times 19 = 19 is the nearest. Now subtract 19 from 30 to get reminder 11. Add 1 to quotient.
\begin{array}{l}\phantom{19)}021\phantom{7}\\19\overline{)4100}\\\phantom{19)}\underline{\phantom{}38\phantom{99}}\\\phantom{19)9}30\\\phantom{19)}\underline{\phantom{9}19\phantom{9}}\\\phantom{19)9}110\\\end{array}
Use the 4^{th} digit 0 from dividend 4100
\begin{array}{l}\phantom{19)}0215\phantom{8}\\19\overline{)4100}\\\phantom{19)}\underline{\phantom{}38\phantom{99}}\\\phantom{19)9}30\\\phantom{19)}\underline{\phantom{9}19\phantom{9}}\\\phantom{19)9}110\\\phantom{19)}\underline{\phantom{99}95\phantom{}}\\\phantom{19)99}15\\\end{array}
Find closest multiple of 19 to 110. We see that 5 \times 19 = 95 is the nearest. Now subtract 95 from 110 to get reminder 15. Add 5 to quotient.
\text{Quotient: }215 \text{Reminder: }15
Since 15 is less than 19, stop the division. The reminder is 15. The topmost line 0215 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 215.
