Streszczenie
We consider subrings $A$ of the ring of formal power series. They are defined by growth conditions on coefficients such as, for instance, Gevrey conditions. We prove a Weierstrass–Hironaka division theorem for such subrings. Moreover, given an ideal ${\mathcal I}$ of $A$ and a series $f$ in $A$ we prove the existence in $A$ of a unique remainder $r$ modulo ${\mathcal I}.$ As a consequence, we get a new proof of the noetherianity of $A.$
