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

1. We assume, that the number 1115.23 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 1115.23, so we can write it down as 100%=1115.23.
4. We know, that x% equals 321.15 of the output value, so we can write it down as x%=321.15.
5. Now we have two simple equations:
1) 100%=1115.23
2) x%=321.15
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%=1115.23/321.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 321.15 is what percent of 1115.23

(100/x)*x=(1115.23/321.15)*x       - we multiply both sides of the equation by x
100=3.472614043282*x       - we divide both sides of the equation by (3.472614043282) to get x
100/3.472614043282=x
28.796750446096=x
x=28.796750446096

now we have:
