\begin{array}{l}\phantom{10)}\phantom{1}\\10\overline{)162}\\\end{array}
Use the 1^{st} digit 1 from dividend 162
\begin{array}{l}\phantom{10)}0\phantom{2}\\10\overline{)162}\\\end{array}
Since 1 is less than 10, use the next digit 6 from dividend 162 and add 0 to the quotient
\begin{array}{l}\phantom{10)}0\phantom{3}\\10\overline{)162}\\\end{array}
Use the 2^{nd} digit 6 from dividend 162
\begin{array}{l}\phantom{10)}01\phantom{4}\\10\overline{)162}\\\phantom{10)}\underline{\phantom{}10\phantom{9}}\\\phantom{10)9}6\\\end{array}
Find closest multiple of 10 to 16. We see that 1 \times 10 = 10 is the nearest. Now subtract 10 from 16 to get reminder 6. Add 1 to quotient.
\begin{array}{l}\phantom{10)}01\phantom{5}\\10\overline{)162}\\\phantom{10)}\underline{\phantom{}10\phantom{9}}\\\phantom{10)9}62\\\end{array}
Use the 3^{rd} digit 2 from dividend 162
\begin{array}{l}\phantom{10)}016\phantom{6}\\10\overline{)162}\\\phantom{10)}\underline{\phantom{}10\phantom{9}}\\\phantom{10)9}62\\\phantom{10)}\underline{\phantom{9}60\phantom{}}\\\phantom{10)99}2\\\end{array}
Find closest multiple of 10 to 62. We see that 6 \times 10 = 60 is the nearest. Now subtract 60 from 62 to get reminder 2. Add 6 to quotient.
\text{Quotient: }16 \text{Reminder: }2
Since 2 is less than 10, stop the division. The reminder is 2. The topmost line 016 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 16.
