Finding Tongue Weight on a Trailer with Multiple Axles??

Can anyone please help me in figuring out how to find the weight placed on multiple points / fulcrums. I already know the formula for two points: (total weight) x (dist. from CG to fulcrum) / (distance between fulcrum points) = (weight on fulcrum a or fulcrum b). Now I have been trying to figure out how this changes once I have more fulcrum points. I would greatly appreciate anyone who can help!

A real world application would be finding the weight on the trailer tongue weight and then the weight placed on axle one and axle two and so on.

For example: I have a total weight of 3,353 lbs. The center of the axles are 130.563" from the coupler. The entire CG is 15.453" toward the coupler from the center of the axles. The axles are 33.5" apart.
