1. We assume, that the number 1266.78 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 1266.78, so we can write it down as 100%=1266.78.
4. We know, that x% equals 866.25 of the output value, so we can write it down as x%=866.25.
5. Now we have two simple equations:
1) 100%=1266.78
2) x%=866.25
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%=1266.78/866.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 866.25 is what percent of 1266.78
