Answer: 0.0485
Explanation:
Shift the decimal points of both 4 and 82.4 to the right by 1 decimal place.
(This is needed to convert 82.4 to 824, since long division must divide by a whole number.)
\frac{40}{824}
824
40
2 Set up the long division.
8 2 4 | 4 0
3 Calculate 4000 ÷ 824, which is 4 with a remainder of 704.
