Creating a list that shows the numerical values not in boolean form

Based from the equation I used in the code below, I found how many values are divisible by 5. However, this is in boolean form. I only know how many are divisible by 5. I need to formulate a conjecture by exploring the values, but I’m having trouble figuring out how to create a list that gives me the numerical values that are divisible by 5 based from given function. Here’s is my program.

expn = Flatten[Table[1^n + 2^n + 3^n + 4^n, {n, 1, 10000}]]; sumpowern = Mod[Total /@ expn, 5] ; Count[sumpowern, 0] posints = Length[Select[Divisible[Total /@ expn , 5], TrueQ]]
