Where are all the google search results?

So its a common thing I see everyday. When I do a google search , it shows millions of results being found. But as and when I keep exploring the following pages. All the results are just over in like 13-18 pages (~200 search results).

So why is it so that the first page shows such a huge number of millions but then all I get is 200-300 results.

And is there some way to view the remaining results.

Thanks
