Division (mathematics) - Wikipedia
https://en.wikipedia.org/wiki/Division_(mathematics)Euclidean division is the mathematical formulation of the outcome of the usual process of division of integers. It asserts that, given two integers, a, the dividend, and b, the divisor, such that b ≠ 0, there are unique integers q, the quotient, and r, the remainder, such that a = bq + r and 0 ≤ r < |b|, where |b| denotes the absolute value of b. Integers are not closedunder division. Apart from division by zero being undefined, the quotient i…
