\begin{array}{l}\phantom{15)}\phantom{1}\\15\overline{)62}\\\end{array}
Use the 1^{st} digit 6 from dividend 62
\begin{array}{l}\phantom{15)}0\phantom{2}\\15\overline{)62}\\\end{array}
Since 6 is less than 15, use the next digit 2 from dividend 62 and add 0 to the quotient
\begin{array}{l}\phantom{15)}0\phantom{3}\\15\overline{)62}\\\end{array}
Use the 2^{nd} digit 2 from dividend 62
\begin{array}{l}\phantom{15)}04\phantom{4}\\15\overline{)62}\\\phantom{15)}\underline{\phantom{}60\phantom{}}\\\phantom{15)9}2\\\end{array}
Find closest multiple of 15 to 62. We see that 4 \times 15 = 60 is the nearest. Now subtract 60 from 62 to get reminder 2. Add 4 to quotient.
\text{Quotient: }4 \text{Reminder: }2
Since 2 is less than 15, stop the division. The reminder is 2. The topmost line 04 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 4.
