Where can I find information about the ~82% of U-235 nuclear fission happening and ~18% not happening?

Where did you find those numbers? What do these percentages correspond? like 82% of what?

What do you want to choose as denominator?

yea I figured that it was somewhat related to ## \dfrac{\sigma (\text{slow }n \text{ fission})}{\sigma (\text{slow }n \text{ total})} \approx 84 \%## the other important processes are just elastic scattering and production of U-236* which decays via gamma to U-236
