Well, that's a pretty broad question.
It takes as long as you need to prepare, basically. Look at the deadlines for the schools you're looking at. If they're US schools, semesters generally start in the fall but spring enrollment is sometimes possible. Let's say you're shooting for a fall enrollment date. Many schools now have three different selection "rounds" to apply for, with different deadlines. Selection varies by school, but usually the program selects a certain percentage from each round to interview. Some programs (like Kellogg) vary rounds by interview location choice - that is, if you request an interview off or on campus.
In whatever case, check the round deadlines for your chosen schools. Then, if you haven't taken the GMAT, schedule to take it before the deadline - generally well before to give yourself another chance to take it if you flop.
During this pre-application time, you want to get the rest of your application packages ready: get letters of recommendation, work up your personal statements, get transcripts, etc.
Some find that at whatever point they start getting their package, they don't have enough time to get everything together - in which case they push their application to the following year.
As for getting a good result, that will depend on your profile and what schools you are applying for. Check other posts on this message board and the articles here for more info.
