It's not really that hard. Round it to 4000/500 and you get 8 so you can safely assume the answer will be around 8. Take 473 times 8 and you get 3784. 3900-3784=116. 116/473 is about 1/4 so I assume the answer is around 8.25 and actually doing the division you get 8.24524 and that's pretty damn close to 8.25. It's not that hard.
The calculator can reduce any fraction, and you are still annoyed by the fact that you have one more key to press to get a decimal approximation? Screw you, JonTron.
