To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 555.75 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 555.75, so we can write it down as 100%=555.75.

5. Now we have two simple equations:
1) 100%=555.75
2) x%=866.97
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=555.75/866.97
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 866.97 is what percent of 555.75

100%/x%=555.75/866.97
(100/x)*x=(555.75/866.97)*x       - we multiply both sides of the equation by x
100=0.64102564102564*x       - we divide both sides of the equation by (0.64102564102564) to get x
100/0.64102564102564=x
156=x
x=156

now we have:
866.97 is 156% of 555.75
