Below is an example dataset. I want to create multiple columns representing the percentage calculated by taking the columns that end in a number (e.g. newTotalCo1) and dividing them by newTotalCLOTotal. That way, if I add up the percentages ACROSS the rows, it equals 100%. After doing that, I will drop the count numbers and reshape the percentage data into a long format.

For example - newTotalCo1/newTotalCLOTotal newTotalCo2/newTotalCLOTotal

Competency CoPercent1 CoPercent 2 CoPercent3
1 0 .105 .263
2 .143 0 .238
