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: [70.873, 45.792, 50.181, 56.439, -5.28, -61.954, -33.514, 228.689, 57.748, -6.345]
A:
[ 0.176  0.114  0.125  0.14  -0.013 -0.154 -0.083  0.568  0.143 -0.016]
