In this task, you will be given a list of numbers. The goal is to divide all the numbers in the list by a constant such that the sum of the resulting list is 1. The output should be rounded to 3 decimals.

Example input: [1, 2, 3]
Example output: [0.167, 0.333, 0.500]
Example explanation: The output list sums to 1.0 and has the same weight as the input 0.333 is twice as large as 0.167, .5 is 3 times as large as 0.167, and 0.5 is 1.5 times as large as 0.333. This is a good example.
Q: [91.623, -14.37, 64.773, 245.88, 60.601, -13.706, 231.179, -40.931]
A:
[ 0.147 -0.023  0.104  0.393  0.097 -0.022  0.37  -0.065]
