(Complex number modulo Complex Number) $\mathbb{C} /n \mathbb{C}$

Question

i know there is a post about $\mathbb{C} / \mathbb{Z}$, but what elements does $\mathbb{C} /n \mathbb{C}$ contain?

Answer 1

Every complex number $z$ is a multiply of every other complex number $w$ over $\mathbb C$. $z = z/w * w$.

So your quotient is a special case with $w = n$. Thus, the quotient is actually the trivial group $\{e\}$.
