Find closest multiple of $70$ to $392$. We see that $5 \times 70 = 350$ is the nearest. Now subtract $350$ from $392$ to get reminder $42$. Add $5$ to quotient.
Find closest multiple of $70$ to $420$. We see that $6 \times 70 = 420$ is the nearest. Now subtract $420$ from $420$ to get reminder $0$. Add $6$ to quotient.
Since $0$ is less than $70$, stop the division. The reminder is $0$. The topmost line $0056$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $56$.
