I'd guess, much smaller percentage than in Europe, where many neighboring countries speak different languages. Why Russians should study foreign language if they are not going to use that - and that's the case for large percentage of population? It's similar to US in that regard - almost all know English, that's enough at home, and usually enough in neighboring Canada, and the primary foreign language is Spanish, probably because another major neighbour, Mexico, speaks Spanish.

Google Translate is pretty good :) but distinctively worse still than the native tongue.
