You'll be hard-pressed to find Russian subtitles for Russian TV, only really popular Russian movies have subtitles (which you can easily find at subtitleseeker or subscene) or Hollywood films that are dubbed in Russian also have subtitles (although not always sync between the text and the dubbing). I doubt you'll find Russian subtitles for a Russian TV series (like интерны), I tried really hard and came up with nothing. Russia just doesn't bother with subtitles.
