\begin{array}{l}\phantom{45)}\phantom{1}\\45\overline{)350}\\\end{array}
Use the 1^{st} digit 3 from dividend 350
\begin{array}{l}\phantom{45)}0\phantom{2}\\45\overline{)350}\\\end{array}
Since 3 is less than 45, use the next digit 5 from dividend 350 and add 0 to the quotient
\begin{array}{l}\phantom{45)}0\phantom{3}\\45\overline{)350}\\\end{array}
Use the 2^{nd} digit 5 from dividend 350
\begin{array}{l}\phantom{45)}00\phantom{4}\\45\overline{)350}\\\end{array}
Since 35 is less than 45, use the next digit 0 from dividend 350 and add 0 to the quotient
\begin{array}{l}\phantom{45)}00\phantom{5}\\45\overline{)350}\\\end{array}
Use the 3^{rd} digit 0 from dividend 350
\begin{array}{l}\phantom{45)}007\phantom{6}\\45\overline{)350}\\\phantom{45)}\underline{\phantom{}315\phantom{}}\\\phantom{45)9}35\\\end{array}
Find closest multiple of 45 to 350. We see that 7 \times 45 = 315 is the nearest. Now subtract 315 from 350 to get reminder 35. Add 7 to quotient.
\text{Quotient: }7 \text{Reminder: }35
Since 35 is less than 45, stop the division. The reminder is 35. The topmost line 007 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 7.
