\begin{array}{l}\phantom{32)}\phantom{1}\\32\overline{)128}\\\end{array}
Use the 1^{st} digit 1 from dividend 128
\begin{array}{l}\phantom{32)}0\phantom{2}\\32\overline{)128}\\\end{array}
Since 1 is less than 32, use the next digit 2 from dividend 128 and add 0 to the quotient
\begin{array}{l}\phantom{32)}0\phantom{3}\\32\overline{)128}\\\end{array}
Use the 2^{nd} digit 2 from dividend 128
\begin{array}{l}\phantom{32)}00\phantom{4}\\32\overline{)128}\\\end{array}
Since 12 is less than 32, use the next digit 8 from dividend 128 and add 0 to the quotient
\begin{array}{l}\phantom{32)}00\phantom{5}\\32\overline{)128}\\\end{array}
Use the 3^{rd} digit 8 from dividend 128
\begin{array}{l}\phantom{32)}004\phantom{6}\\32\overline{)128}\\\phantom{32)}\underline{\phantom{}128\phantom{}}\\\phantom{32)999}0\\\end{array}
Find closest multiple of 32 to 128. We see that 4 \times 32 = 128 is the nearest. Now subtract 128 from 128 to get reminder 0. Add 4 to quotient.
\text{Quotient: }4 \text{Reminder: }0
Since 0 is less than 32, stop the division. The reminder is 0. The topmost line 004 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 4.
