It is called the decimal point. We say "point". For example 3.25 cakes is "three point two five cakes". The decimal point shows that the number on its left is the last whole number. In the above example, you have three whole cakes. The number in the next place on the right tells you how many tenths of a cake there are, in this case two-tenths of a cake. The number in the next place on the right tells you how many hundredths of a cake there are, in this case five-hundredths of a cake. 0.1 (zero point one) is one tenth.
0.04 (zero point zero four) is four hundredths.

It is NOT a place holder though, for really big (or small) numbers it can help find the place value. It is called a separator or delimiter.
There are 3 identical digits in the units period. If the number started with 23 then 2 + 3 = 5 and 20 - 5 = 15 which is divisible by three. If the number started with 24 then 2 + 4 = 6 and 20 - 6 = 14 is not divisible by 3. So the number is 23,000,555.
