2600 / (4.184 x 25.6 )  =  24.27402008 (approximately)

2600 has 2 significant digits (ignore the ending zeros).

4.184 has 4 significant digits.

25.6 has 3 significant digits.

The answer cannot have more significant digits than the least of the numbers in the problem; in this case, two significant digits.

So, keeping only two significant digits, the answer rounds to 24.
