The Division Theorem

For any integer a and positive integer d, there exist unique integers q (quotient) and r (remainder) such that:

a = d × q + r

q = 101 div 11 = 9
r = 101 mod 11 = 2
101 = (11 × 9) + 2

The Prime Number Theorem

Primes become rarer as numbers get larger. We estimate the count of primes π(x) using the formula: x / ln(x).
