Why is gta5 takes ages to download?

I'm finally aloud to borrow my mums and I put it in. I know it's big but I didn't exspect it to take this long. It's been 15 minits and it's about half way on the bottom like and 90 on the to. It also says 8/11. Why does it take so long and how long should it take. Games don't us daly take this long exspect maybe minecraft after a big update.

There are a lot of updates and how long they take depends on how fast your internet connection is, the updates will take as much as 30 minutes to download with a slow connection then the game installs and that takes another 15 minutes as it is copying almost 9GB from the disc to the hard drive then installing that data

the 8 / 11 means you have downloaded 8 of the 11 updates for gta5, 3 left then the game install

If your internet is busy, it will take longer to download.

Also not all Internet speeds are the same. Someone could be subscribed to 1 megabit internet, where at your home it's 15 megabit!
