Find closest multiple of $18$ to $18$. We see that $1 \times 18 = 18$ is the nearest. Now subtract $18$ from $18$ to get reminder $0$. Add $1$ to quotient.
Since $0$ is less than $18$, stop the division. The reminder is $0$. The topmost line $01$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $1$.
