Eighty-three million, seven hundred nine thousand, eight hundred ninety.

Explanation:

The number is divided into three sections called "periods."

There are many more periods than this problem has.

Each period has its own name.
[millions] [thousands] [hundreds]
[ . . 83 . .] [. . . 709 . . .] [ . . .890. . ]

To determine what period each group of 3 numbers is in:

1) Start at the decimal point
2) Count off the last three numbers, going to the left
3) Say "Hundreds!" as the name for that group of three
4) Now say "Thousands!" for the next group of three numbers
5) Keep on counting off groups of three. The next one to the left is "Millions!"
6) If you had another group of three, it would be named "Billions!"

Here is a true news story about a large number:

Pennsylvania woman gets $284,460,000,000 electric bill

The amount due is named
#"284 billion, four hundred sixty million dollars"#

At #$200# per month, this bill will be paid up in #118,525,000# years
("One hundred eighteen million, five hundred twenty five thousand" years)

..............................

We don't say "and" for any numbers.
"And" is the name of the decimal place.

Example:

405, 214,360.2

[ ...............405.......................] [ ...........................214 .........................]
[four hundred five million] [two hundred fourteen thousand]

[ ............. 360 .............]     #․#    [ ....... 2 ........]
[three hundred sixty] AND [two tenths]
