.99999 repeating to infinity is exactly equal to 1

Here is my proof.

1 divided by 3 is .3333 repeating to infinity.

3 times .3333 repeating is .99999 repeating.

Therefore .9999 repeating is exactly equal to 1.

The fact that a number can be exactly equal to a different number is sort of mind boggling.
