When you come to a comma, you say, "trillion, billion, million, thousand. Thus the number is 9 trillion, nine hundred ninety-nine billion, nine hundred ninety-nine million, nine hundred ninety-nine thousand, nine hundred ninety-nine. You don't say and until you come to the decimal. Trillion has 4 commas, billion has three, million has two and thousands has one. Some countries have variations on the names such as millard, I believe.
