\begin{array}{l}\phantom{18)}\phantom{1}\\18\overline{)126}\\\end{array}
Use the 1^{st} digit 1 from dividend 126
\begin{array}{l}\phantom{18)}0\phantom{2}\\18\overline{)126}\\\end{array}
Since 1 is less than 18, use the next digit 2 from dividend 126 and add 0 to the quotient
\begin{array}{l}\phantom{18)}0\phantom{3}\\18\overline{)126}\\\end{array}
Use the 2^{nd} digit 2 from dividend 126
\begin{array}{l}\phantom{18)}00\phantom{4}\\18\overline{)126}\\\end{array}
Since 12 is less than 18, use the next digit 6 from dividend 126 and add 0 to the quotient
\begin{array}{l}\phantom{18)}00\phantom{5}\\18\overline{)126}\\\end{array}
Use the 3^{rd} digit 6 from dividend 126
\begin{array}{l}\phantom{18)}007\phantom{6}\\18\overline{)126}\\\phantom{18)}\underline{\phantom{}126\phantom{}}\\\phantom{18)999}0\\\end{array}
Find closest multiple of 18 to 126. We see that 7 \times 18 = 126 is the nearest. Now subtract 126 from 126 to get reminder 0. Add 7 to quotient.
\text{Quotient: }7 \text{Reminder: }0
Since 0 is less than 18, stop the division. The reminder is 0. The topmost line 007 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 7.
