Find closest multiple of $15$ to $30$. We see that $2 \times 15 = 30$ is the nearest. Now subtract $30$ from $30$ to get reminder $0$. Add $2$ to quotient.
Since $0$ is less than $15$, stop the division. The reminder is $0$. The topmost line $02$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $2$.
