\begin{array}{l}\phantom{25)}\phantom{1}\\25\overline{)35}\\\end{array}
Use the 1^{st} digit 3 from dividend 35
\begin{array}{l}\phantom{25)}0\phantom{2}\\25\overline{)35}\\\end{array}
Since 3 is less than 25, use the next digit 5 from dividend 35 and add 0 to the quotient
\begin{array}{l}\phantom{25)}0\phantom{3}\\25\overline{)35}\\\end{array}
Use the 2^{nd} digit 5 from dividend 35
\begin{array}{l}\phantom{25)}01\phantom{4}\\25\overline{)35}\\\phantom{25)}\underline{\phantom{}25\phantom{}}\\\phantom{25)}10\\\end{array}
Find closest multiple of 25 to 35. We see that 1 \times 25 = 25 is the nearest. Now subtract 25 from 35 to get reminder 10. Add 1 to quotient.
\text{Quotient: }1 \text{Reminder: }10
Since 10 is less than 25, stop the division. The reminder is 10. The topmost line 01 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.
