Find closest multiple of $10$ to $68$. We see that $6 \times 10 = 60$ is the nearest. Now subtract $60$ from $68$ to get reminder $8$. Add $6$ to quotient.
Find closest multiple of $10$ to $83$. We see that $8 \times 10 = 80$ is the nearest. Now subtract $80$ from $83$ to get reminder $3$. Add $8$ to quotient.
Since $3$ is less than $10$, stop the division. The reminder is $3$. The topmost line $068$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $68$.
