\begin{array}{l}\phantom{25)}\phantom{1}\\25\overline{)40075}\\\end{array}
Use the 1^{st} digit 4 from dividend 40075
\begin{array}{l}\phantom{25)}0\phantom{2}\\25\overline{)40075}\\\end{array}
Since 4 is less than 25, use the next digit 0 from dividend 40075 and add 0 to the quotient
\begin{array}{l}\phantom{25)}0\phantom{3}\\25\overline{)40075}\\\end{array}
Use the 2^{nd} digit 0 from dividend 40075
\begin{array}{l}\phantom{25)}01\phantom{4}\\25\overline{)40075}\\\phantom{25)}\underline{\phantom{}25\phantom{999}}\\\phantom{25)}15\\\end{array}
Find closest multiple of 25 to 40. We see that 1 \times 25 = 25 is the nearest. Now subtract 25 from 40 to get reminder 15. Add 1 to quotient.
\begin{array}{l}\phantom{25)}01\phantom{5}\\25\overline{)40075}\\\phantom{25)}\underline{\phantom{}25\phantom{999}}\\\phantom{25)}150\\\end{array}
Use the 3^{rd} digit 0 from dividend 40075
\begin{array}{l}\phantom{25)}016\phantom{6}\\25\overline{)40075}\\\phantom{25)}\underline{\phantom{}25\phantom{999}}\\\phantom{25)}150\\\phantom{25)}\underline{\phantom{}150\phantom{99}}\\\phantom{25)999}0\\\end{array}
Find closest multiple of 25 to 150. We see that 6 \times 25 = 150 is the nearest. Now subtract 150 from 150 to get reminder 0. Add 6 to quotient.
\begin{array}{l}\phantom{25)}016\phantom{7}\\25\overline{)40075}\\\phantom{25)}\underline{\phantom{}25\phantom{999}}\\\phantom{25)}150\\\phantom{25)}\underline{\phantom{}150\phantom{99}}\\\phantom{25)999}7\\\end{array}
Use the 4^{th} digit 7 from dividend 40075
\begin{array}{l}\phantom{25)}0160\phantom{8}\\25\overline{)40075}\\\phantom{25)}\underline{\phantom{}25\phantom{999}}\\\phantom{25)}150\\\phantom{25)}\underline{\phantom{}150\phantom{99}}\\\phantom{25)999}7\\\end{array}
Since 7 is less than 25, use the next digit 5 from dividend 40075 and add 0 to the quotient
\begin{array}{l}\phantom{25)}0160\phantom{9}\\25\overline{)40075}\\\phantom{25)}\underline{\phantom{}25\phantom{999}}\\\phantom{25)}150\\\phantom{25)}\underline{\phantom{}150\phantom{99}}\\\phantom{25)999}75\\\end{array}
Use the 5^{th} digit 5 from dividend 40075
\begin{array}{l}\phantom{25)}01603\phantom{10}\\25\overline{)40075}\\\phantom{25)}\underline{\phantom{}25\phantom{999}}\\\phantom{25)}150\\\phantom{25)}\underline{\phantom{}150\phantom{99}}\\\phantom{25)999}75\\\phantom{25)}\underline{\phantom{999}75\phantom{}}\\\phantom{25)99999}0\\\end{array}
Find closest multiple of 25 to 75. We see that 3 \times 25 = 75 is the nearest. Now subtract 75 from 75 to get reminder 0. Add 3 to quotient.
\text{Quotient: }1603 \text{Reminder: }0
Since 0 is less than 25, stop the division. The reminder is 0. The topmost line 01603 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1603.
