You are allowed to enter the country as many times you want over the 5 years. Each time you enter, you receive a 180 day stamp, which gives you 180 days. With every 180 day stamp, you can then extend one time for an additional 180 days. If you do extend, you have to leave the country at the end of the 180 day extension, but you can return and start all over. For me, I have entered and left 6+ times in last 6 months and each time I get a new 180 day stamp.
