\begin{array}{l}\phantom{60)}\phantom{1}\\60\overline{)422}\\\end{array}
Use the 1^{st} digit 4 from dividend 422
\begin{array}{l}\phantom{60)}0\phantom{2}\\60\overline{)422}\\\end{array}
Since 4 is less than 60, use the next digit 2 from dividend 422 and add 0 to the quotient
\begin{array}{l}\phantom{60)}0\phantom{3}\\60\overline{)422}\\\end{array}
Use the 2^{nd} digit 2 from dividend 422
\begin{array}{l}\phantom{60)}00\phantom{4}\\60\overline{)422}\\\end{array}
Since 42 is less than 60, use the next digit 2 from dividend 422 and add 0 to the quotient
\begin{array}{l}\phantom{60)}00\phantom{5}\\60\overline{)422}\\\end{array}
Use the 3^{rd} digit 2 from dividend 422
\begin{array}{l}\phantom{60)}007\phantom{6}\\60\overline{)422}\\\phantom{60)}\underline{\phantom{}420\phantom{}}\\\phantom{60)99}2\\\end{array}
Find closest multiple of 60 to 422. We see that 7 \times 60 = 420 is the nearest. Now subtract 420 from 422 to get reminder 2. Add 7 to quotient.
\text{Quotient: }7 \text{Reminder: }2
Since 2 is less than 60, stop the division. The reminder is 2. The topmost line 007 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 7.
