Find closest multiple of $91$ to $568$. We see that $6 \times 91 = 546$ is the nearest. Now subtract $546$ from $568$ to get reminder $22$. Add $6$ to quotient.
Since $22$ is less than $91$, stop the division. The reminder is $22$. The topmost line $006$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $6$.
