Why is 3/3 equal to 1?
Ok, so 1/3 is 0.33333 forever. 2/3 is 0.6666 forever. So, if that's the case, why is 3/3=1 and not 0.99999 forever? Where does the last little bit get added to 3/3 to have it equal 1?

It’s a failure of numerical systems, .33333 = 1/3. It’s because 1/3 can’t be expressed in decimal format that we need it in the first place. Numbers are only useful as much as they can describe reality, and we have different numerical concepts to describe different phenomena. There’s no rhyme or reason for it, and you won’t be able to find one.

You can divide 3 by 3 just once, therefore 1
Are you retarded, OP?

It doesn't.
You're talking about two different systems of notation, i.e., two different dialects of the same language that have different syntax and rules.
Decimal notation is the expansion of the rational term. The notation itself is a limited format, it is so precise that it generates an infinite repeating sequence that you are using your intuition to "summarize" and assume is equal to 1/3. That is called "taking the limit" of a sequence that demonstrates "convergence". In this case, the sequence converges on a number that cannot be represented in decimal notation, so you must use a different kind of notation to represent it.
This happens constantly, everywhere in mathematics. Set theory has to be translated into category theory and the notation is not the same. Algebraic geometry is not the same as the algebra you learned in high school, and so forth.
You are incorrectly assuming that the two numbers are using the same notation and mean the same thing. They do not mean the same thing. There is no "last little bit" that gets "added to 3/3". Instead, you translate French into English. 0.333333~ in decimal notation, translated into the notation used for rational numbers, making it "equivalent" (which is not at all the same thing as "equal").

Take an intro to calculus class, buddy. Or read any intro book, there's too many out there cause it's an easy but important subject for science+math.
Start with a whole cake. Eat half the cake. Eat half of what remains. Eat half of what remains. Continue ad infinitum. Don't you basically eat the whole cake? Start with a whole cake, 1. Eat 9/10 of it, eat 9/10 of what remains, continue ad infinitum. Don't you eat all of 1?
.9999999999... -> 1
.00000000000...1 -> 0
You want to find the area of a circle. Fill it with a 3-polygon (triangle). What's the area? Now do a 4-polygon (square) instead. Now a 5-polygon instead. Continue ad infinitum. Don't you basically get the whole circle?
