Find closest multiple of $17$ to $84$. We see that $4 \times 17 = 68$ is the nearest. Now subtract $68$ from $84$ to get reminder $16$. Add $4$ to quotient.
Since $16$ is less than $17$, stop the division. The reminder is $16$. The topmost line $04$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $4$.
