\begin{array}{l}\phantom{35)}\phantom{1}\\35\overline{)42}\\\end{array}
Use the 1^{st} digit 4 from dividend 42
\begin{array}{l}\phantom{35)}0\phantom{2}\\35\overline{)42}\\\end{array}
Since 4 is less than 35, use the next digit 2 from dividend 42 and add 0 to the quotient
\begin{array}{l}\phantom{35)}0\phantom{3}\\35\overline{)42}\\\end{array}
Use the 2^{nd} digit 2 from dividend 42
\begin{array}{l}\phantom{35)}01\phantom{4}\\35\overline{)42}\\\phantom{35)}\underline{\phantom{}35\phantom{}}\\\phantom{35)9}7\\\end{array}
Find closest multiple of 35 to 42. We see that 1 \times 35 = 35 is the nearest. Now subtract 35 from 42 to get reminder 7. Add 1 to quotient.
\text{Quotient: }1 \text{Reminder: }7
Since 7 is less than 35, stop the division. The reminder is 7. The topmost line 01 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.
