To find the decimal expansion of $\frac{141}{400}$, I can divide 141 by 400 using long division or a calculator. Alternatively, I can notice that $\frac{141}{400} = \frac{35.25}{100} = 0.3525$, which is easier to work with. Either way, I get the same decimal expansion: $0.3525$. The last nonzero digit to the right of the decimal point is 5. 
What is the last nonzero digit to the right of the decimal point in the decimal expansion of $\frac{141}{400}$?
