\begin{array}{l}\phantom{130)}\phantom{1}\\130\overline{)520}\\\end{array}
Use the 1^{st} digit 5 from dividend 520
\begin{array}{l}\phantom{130)}0\phantom{2}\\130\overline{)520}\\\end{array}
Since 5 is less than 130, use the next digit 2 from dividend 520 and add 0 to the quotient
\begin{array}{l}\phantom{130)}0\phantom{3}\\130\overline{)520}\\\end{array}
Use the 2^{nd} digit 2 from dividend 520
\begin{array}{l}\phantom{130)}00\phantom{4}\\130\overline{)520}\\\end{array}
Since 52 is less than 130, use the next digit 0 from dividend 520 and add 0 to the quotient
\begin{array}{l}\phantom{130)}00\phantom{5}\\130\overline{)520}\\\end{array}
Use the 3^{rd} digit 0 from dividend 520
\begin{array}{l}\phantom{130)}004\phantom{6}\\130\overline{)520}\\\phantom{130)}\underline{\phantom{}520\phantom{}}\\\phantom{130)999}0\\\end{array}
Find closest multiple of 130 to 520. We see that 4 \times 130 = 520 is the nearest. Now subtract 520 from 520 to get reminder 0. Add 4 to quotient.
\text{Quotient: }4 \text{Reminder: }0
Since 0 is less than 130, stop the division. The reminder is 0. The topmost line 004 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 4.
