\begin{array}{l}\phantom{60)}\phantom{1}\\60\overline{)450}\\\end{array}
Use the 1^{st} digit 4 from dividend 450
\begin{array}{l}\phantom{60)}0\phantom{2}\\60\overline{)450}\\\end{array}
Since 4 is less than 60, use the next digit 5 from dividend 450 and add 0 to the quotient
\begin{array}{l}\phantom{60)}0\phantom{3}\\60\overline{)450}\\\end{array}
Use the 2^{nd} digit 5 from dividend 450
\begin{array}{l}\phantom{60)}00\phantom{4}\\60\overline{)450}\\\end{array}
Since 45 is less than 60, use the next digit 0 from dividend 450 and add 0 to the quotient
\begin{array}{l}\phantom{60)}00\phantom{5}\\60\overline{)450}\\\end{array}
Use the 3^{rd} digit 0 from dividend 450
\begin{array}{l}\phantom{60)}007\phantom{6}\\60\overline{)450}\\\phantom{60)}\underline{\phantom{}420\phantom{}}\\\phantom{60)9}30\\\end{array}
Find closest multiple of 60 to 450. We see that 7 \times 60 = 420 is the nearest. Now subtract 420 from 450 to get reminder 30. Add 7 to quotient.
\text{Quotient: }7 \text{Reminder: }30
Since 30 is less than 60, stop the division. The reminder is 30. The topmost line 007 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 7.
