I must have answered that because I figured obitonye would know Russian – can't remember now, almost a year later. I have no idea in your case, but in English, they say 'it went well' to mean that some event was successful or had a good outcome. Det gick bra works the same way in Swedish.
For instance, if someone knows you've been to the dentist, they might ask you afterwards Hur gick det?, in English they might say 'How did it go?', meaning what was it like, how did it turn out or something like that.
