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

1. We assume, that the number 875000 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 875000, so we can write it down as 100%=875000.
4. We know, that x% equals 66840 of the output value, so we can write it down as x%=66840.
5. Now we have two simple equations:
1) 100%=875000
2) x%=66840
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%=875000/66840
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66840 is what percent of 875000

100%/x%=875000/66840
(100/x)*x=(875000/66840)*x       - we multiply both sides of the equation by x
100=13.090963494913*x       - we divide both sides of the equation by (13.090963494913) to get x
100/13.090963494913=x
7.6388571428571=x
x=7.6388571428571

now we have:
