Find closest multiple of $15$ to $21$. We see that $1 \times 15 = 15$ is the nearest. Now subtract $15$ from $21$ to get reminder $6$. Add $1$ to quotient.
Find closest multiple of $15$ to $60$. We see that $4 \times 15 = 60$ is the nearest. Now subtract $60$ from $60$ to get reminder $0$. Add $4$ to quotient.
Since $0$ is less than $15$, stop the division. The reminder is $0$. The topmost line $014$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $14$.
