As already dito, the perfect way is to change the primary of mains transformer from 110 to 220v, and I know this is not expensive.
I think any other CHEAP solution will carry noise, or something else not very good.

It depends on the application. If the 220v is AC mains, the current is low and you don't mind the health risk, you can do it with two resistors. Otherwise I would suggest a 220v to 5V transformer is the best solution.
