Find closest multiple of $25$ to $50$. We see that $2 \times 25 = 50$ is the nearest. Now subtract $50$ from $50$ to get reminder $0$. Add $2$ to quotient.
Find closest multiple of $25$ to $125$. We see that $5 \times 25 = 125$ is the nearest. Now subtract $125$ from $125$ to get reminder $0$. Add $5$ to quotient.
Since $0$ is less than $25$, stop the division. The reminder is $0$. The topmost line $02005$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $2005$.
