1. We assume, that the number 1641.28 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 1641.28, so we can write it down as 100%=1641.28.
4. We know, that x% equals 133.18 of the output value, so we can write it down as x%=133.18.
5. Now we have two simple equations:
1) 100%=1641.28
2) x%=133.18
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%=1641.28/133.18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 133.18 is what percent of 1641.28

(100/x)*x=(1641.28/133.18)*x       - we multiply both sides of the equation by x
100=12.323772338189*x       - we divide both sides of the equation by (12.323772338189) to get x
100/12.323772338189=x
8.1143985182297=x
x=8.1143985182297

now we have:
