Individual digits within a number have place values, not whole numbers.
A single digit in a number can have a place value. A number with several digits cannot.

Let's take, for example the number 10. The '1' is the tens place, and the '0' is the ones place (also refereed to as the 'unit').
No. A zillion is not really a number. It is just an indication of a very large number.

Oh, dude, a zillion? That's like, a made-up number, man. It's not even a real thing in math. So, technically, there are zero zeros in a zillion because it doesn't exist in the first place. But hey, if you wanna make up your own math rules and have a zillion zeros, go for it!
Align the numbers according their place values. Go from left to right (decreasing place values) until the face values of the numbers are different. Then the number with the larger face value in that place is the larger number.

The total number of possible outcomes is the product of the number of values for each event.
Pi cannot be expressed exactly as any fraction (including as a fraction of powers of 10, which is what a decimal fraction is). There are an infinite number of place values in the number 'pi'.

There are not just 5 place values - there are infinitely many.
