\begin{array}{l}\phantom{25)}\phantom{1}\\25\overline{)48}\\\end{array}
Use the 1^{st} digit 4 from dividend 48
\begin{array}{l}\phantom{25)}0\phantom{2}\\25\overline{)48}\\\end{array}
Since 4 is less than 25, use the next digit 8 from dividend 48 and add 0 to the quotient
\begin{array}{l}\phantom{25)}0\phantom{3}\\25\overline{)48}\\\end{array}
Use the 2^{nd} digit 8 from dividend 48
\begin{array}{l}\phantom{25)}01\phantom{4}\\25\overline{)48}\\\phantom{25)}\underline{\phantom{}25\phantom{}}\\\phantom{25)}23\\\end{array}
Find closest multiple of 25 to 48. We see that 1 \times 25 = 25 is the nearest. Now subtract 25 from 48 to get reminder 23. Add 1 to quotient.
\text{Quotient: }1 \text{Reminder: }23
Since 23 is less than 25, stop the division. The reminder is 23. The topmost line 01 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.
