Definition:Quotient (Integer Division)/Real

Definition

Let $x, y \in \R$ be real numbers such that $y \ne 0$.

The quotient of $x$ on division by $y$ is defined as the value of $q$ in the expression:

$\forall x, y \in \R, y \ne 0: \exists! q \in \Z, r \in \R: x = q y + r, 0 \le r < \size y$

From the definition of the Modulo Operation:

$x \bmod y := x - y \floor {\dfrac x y} = r$

it can be seen that the quotient of $x$ on division by $y$ is defined as:

$q = \floor {\dfrac x y}$

The word quotient derives from the Latin word meaning how often.
