What this part means

the sum of each individual stat’s remainder modulo four.

Its job in the formula

R is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

Summed across however many stats receive investment, total stat points bought equals (510 - R)/4 , where R is the sum of each individual stat’s remainder modulo four.

The passage around this formula

…at all. The number of stat points any single invested value E buys is ⌊\lfloor E/4 ⌋\rfloor , which equals (E - (E  mod \bmod 4))/4 . Summed across however many stats receive investment, total stat points bought equals (510 - R)/4 , where R is the sum of each individual stat’s remainder modulo four. Since 510 itself leaves a remainder of 2 when divided by 4, R must also be congruent to 2 modulo 4 for every point of the 510-point budget to be accounted for — and the smallest non-negative value satisfying that congruence…
