Find closest multiple of $11$ to $11$. We see that $1 \times 11 = 11$ is the nearest. Now subtract $11$ from $11$ to get reminder $0$. Add $1$ to quotient.
Find closest multiple of $11$ to $42$. We see that $3 \times 11 = 33$ is the nearest. Now subtract $33$ from $42$ to get reminder $9$. Add $3$ to quotient.
Since $9$ is less than $11$, stop the division. The reminder is $9$. The topmost line $0103$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $103$.
