Find closest multiple of $100$ to $464$. We see that $4 \times 100 = 400$ is the nearest. Now subtract $400$ from $464$ to get reminder $64$. Add $4$ to quotient.
Find closest multiple of $100$ to $648$. We see that $6 \times 100 = 600$ is the nearest. Now subtract $600$ from $648$ to get reminder $48$. Add $6$ to quotient.
Since $48$ is less than $100$, stop the division. The reminder is $48$. The topmost line $0046$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $46$.
