[PQ] divide each row of a column by an item in the same column & add result to new column

Hi,
I am running a lot of analysis, using tables and a lot of formulas.
In the current example, I am running a vertical analysis, which is to divide all items of a column for a fiscal year by a single specific item.
So, in the example file, I want to add a new column for each year and divide each item by the total assets value of that year.
I hope anyone may have a clue about solving it.
