\begin{array}{l}\phantom{35)}\phantom{1}\\35\overline{)245}\\\end{array}
Use the 1^{st} digit 2 from dividend 245
\begin{array}{l}\phantom{35)}0\phantom{2}\\35\overline{)245}\\\end{array}
Since 2 is less than 35, use the next digit 4 from dividend 245 and add 0 to the quotient
\begin{array}{l}\phantom{35)}0\phantom{3}\\35\overline{)245}\\\end{array}
Use the 2^{nd} digit 4 from dividend 245
\begin{array}{l}\phantom{35)}00\phantom{4}\\35\overline{)245}\\\end{array}
Since 24 is less than 35, use the next digit 5 from dividend 245 and add 0 to the quotient
\begin{array}{l}\phantom{35)}00\phantom{5}\\35\overline{)245}\\\end{array}
Use the 3^{rd} digit 5 from dividend 245
\begin{array}{l}\phantom{35)}007\phantom{6}\\35\overline{)245}\\\phantom{35)}\underline{\phantom{}245\phantom{}}\\\phantom{35)999}0\\\end{array}
Find closest multiple of 35 to 245. We see that 7 \times 35 = 245 is the nearest. Now subtract 245 from 245 to get reminder 0. Add 7 to quotient.
\text{Quotient: }7 \text{Reminder: }0
Since 0 is less than 35, stop the division. The reminder is 0. The topmost line 007 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 7.
