International audienceThe aim of this note is to prove estimates on mean values of the number of times that Itô processes observed at discrete times visit small balls in $\er^d$. Our technique, in the infinite horizon case, is inspired by Krylov's arguments in~\cite[Chap.2]{kry80}. In the finite horizon case, motivated by an application in stochastic numerics, we discount the number of visits by a locally exploding coefficient, and our proof involves accurate properties of last passage times at 0 of one dimensional semimartingales
