Find closest multiple of $18$ to $50$. We see that $2 \times 18 = 36$ is the nearest. Now subtract $36$ from $50$ to get reminder $14$. Add $2$ to quotient.
Since $14$ is less than $18$, stop the division. The reminder is $14$. The topmost line $02$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $2$.
