\begin{array}{l}\phantom{40)}\phantom{1}\\40\overline{)148}\\\end{array}
Use the 1^{st} digit 1 from dividend 148
\begin{array}{l}\phantom{40)}0\phantom{2}\\40\overline{)148}\\\end{array}
Since 1 is less than 40, use the next digit 4 from dividend 148 and add 0 to the quotient
\begin{array}{l}\phantom{40)}0\phantom{3}\\40\overline{)148}\\\end{array}
Use the 2^{nd} digit 4 from dividend 148
\begin{array}{l}\phantom{40)}00\phantom{4}\\40\overline{)148}\\\end{array}
Since 14 is less than 40, use the next digit 8 from dividend 148 and add 0 to the quotient
\begin{array}{l}\phantom{40)}00\phantom{5}\\40\overline{)148}\\\end{array}
Use the 3^{rd} digit 8 from dividend 148
\begin{array}{l}\phantom{40)}003\phantom{6}\\40\overline{)148}\\\phantom{40)}\underline{\phantom{}120\phantom{}}\\\phantom{40)9}28\\\end{array}
Find closest multiple of 40 to 148. We see that 3 \times 40 = 120 is the nearest. Now subtract 120 from 148 to get reminder 28. Add 3 to quotient.
\text{Quotient: }3 \text{Reminder: }28
Since 28 is less than 40, stop the division. The reminder is 28. The topmost line 003 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 3.
