How to calculate a division without using DAX

This is a short example of the development created for a specific requirement.

The idea is to have only one measure that provides all the results for the crucial metrics. Everything has been working as expected. (Measure = SUM('Values'[Value])).

However, the client is requesting a new metric that involves a division between two previous results, but with a specific condition: It is not allowed two use DAX for this calculation. The goal is to have this result also contained on the measure used until now. In this example Metric E.

I have been searching for a possible solution, but so far, anything seems to be useful for this purpose. I haven't found a way to calculate this division of calculated results using Power Query or implementing another alternative.

Is there a way to get this result to include it in the global measure?

Regards.
