Labor and pushing?

I'm a first time mom and haven't been to any birthing classes yet. I was just reading a post on here and everyone was saying they labored for a certain numbers of hours and pushed X number of times which lasted so many minutes or hours. Is there a good website to check out to understand this? I thought maybe you would be pushing a lot more and that's why labor is so long?
