Euclidean division

For integers a and b with b not zero, there is a unique quotient q and remainder r such that a equals bq plus r and r lies between 0 and the absolute value of b. It underlies integer division and the Euclidean algorithm.

a = bq + r \quad \text{with } 0 \leq r < |b|

What the symbols mean

the integer being divided (dividend)
the nonzero integer divisor
the unique integer quotient
the unique integer remainder, satisfying $0 \leq r < |b|$
