\begin{array}{l}\phantom{30)}\phantom{1}\\30\overline{)186}\\\end{array}
Use the 1^{st} digit 1 from dividend 186
\begin{array}{l}\phantom{30)}0\phantom{2}\\30\overline{)186}\\\end{array}
Since 1 is less than 30, use the next digit 8 from dividend 186 and add 0 to the quotient
\begin{array}{l}\phantom{30)}0\phantom{3}\\30\overline{)186}\\\end{array}
Use the 2^{nd} digit 8 from dividend 186
\begin{array}{l}\phantom{30)}00\phantom{4}\\30\overline{)186}\\\end{array}
Since 18 is less than 30, use the next digit 6 from dividend 186 and add 0 to the quotient
\begin{array}{l}\phantom{30)}00\phantom{5}\\30\overline{)186}\\\end{array}
Use the 3^{rd} digit 6 from dividend 186
\begin{array}{l}\phantom{30)}006\phantom{6}\\30\overline{)186}\\\phantom{30)}\underline{\phantom{}180\phantom{}}\\\phantom{30)99}6\\\end{array}
Find closest multiple of 30 to 186. We see that 6 \times 30 = 180 is the nearest. Now subtract 180 from 186 to get reminder 6. Add 6 to quotient.
\text{Quotient: }6 \text{Reminder: }6
Since 6 is less than 30, stop the division. The reminder is 6. The topmost line 006 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 6.
