Definition: Euclidean Ring, Generalization of Division With Quotient and Remainder

An integral domain $(R,\cdot,+)$ is called an Euclidean ring, if there is a function, called the Euclidean function, mapping its non-zero elements to the set $\mathbb N$ of natural numbers $f:R\setminus\{0\}\to\mathbb N$ such that for any two elements $a,b\in R$ we have $$a=qb+r$$ with either $r=0$ ($0\in R$) or $f( r) < f(b).$
