Find closest multiple of $16$ to $66$. We see that $4 \times 16 = 64$ is the nearest. Now subtract $64$ from $66$ to get reminder $2$. Add $4$ to quotient.
Find closest multiple of $16$ to $26$. We see that $1 \times 16 = 16$ is the nearest. Now subtract $16$ from $26$ to get reminder $10$. Add $1$ to quotient.
Since $10$ is less than $16$, stop the division. The reminder is $10$. The topmost line $041$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $41$.
