I don’t know if calculators have a function to display remainder. But if it doesn’t, here is a quick way with the calculator, so you don’t have to work it out.

125 /8=15.625

Round down the answer to next whole number, I.e. 15, and multiply it with the denominator.

15 x 8 = 120

Remainder= 125-120 =5
