Find closest multiple of $20$ to $24$. We see that $1 \times 20 = 20$ is the nearest. Now subtract $20$ from $24$ to get reminder $4$. Add $1$ to quotient.
Since $4$ is less than $20$, stop the division. The reminder is $4$. The topmost line $01$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $1$.
