\begin{array}{l}\phantom{49)}\phantom{1}\\49\overline{)147}\\\end{array}
Use the 1^{st} digit 1 from dividend 147
\begin{array}{l}\phantom{49)}0\phantom{2}\\49\overline{)147}\\\end{array}
Since 1 is less than 49, use the next digit 4 from dividend 147 and add 0 to the quotient
\begin{array}{l}\phantom{49)}0\phantom{3}\\49\overline{)147}\\\end{array}
Use the 2^{nd} digit 4 from dividend 147
\begin{array}{l}\phantom{49)}00\phantom{4}\\49\overline{)147}\\\end{array}
Since 14 is less than 49, use the next digit 7 from dividend 147 and add 0 to the quotient
\begin{array}{l}\phantom{49)}00\phantom{5}\\49\overline{)147}\\\end{array}
Use the 3^{rd} digit 7 from dividend 147
\begin{array}{l}\phantom{49)}003\phantom{6}\\49\overline{)147}\\\phantom{49)}\underline{\phantom{}147\phantom{}}\\\phantom{49)999}0\\\end{array}
Find closest multiple of 49 to 147. We see that 3 \times 49 = 147 is the nearest. Now subtract 147 from 147 to get reminder 0. Add 3 to quotient.
\text{Quotient: }3 \text{Reminder: }0
Since 0 is less than 49, stop the division. The reminder is 0. The topmost line 003 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 3.
