cake goes to infinity
I just found to never run out of cakes
Wait, wouldn't you eventually end up with a cake that's untouched? Like, at the limit there won't be any people to give the cake to... (I don't think this is a very good analogy for why you can't divide by 0.)

As a workaround, take the limit of the thing you are trying to divide the thing by 0 and divide it by x as x approaches 0

The old fashioned notion of dividing a whole slice for N people is not going to do us good in this, we need to break the problem down to its core. When you are slicing a cake, you are taking and series of angles of a circles in parts and distributing them one by one. The procedure is the following: You take the whole 360 deg angle and divide it by the number of people you want to give it to, then you trace that much from the starting point around it, and give that much you traced to the first person. Then repeat until you got no cake left. So consider this:

You have 2pi of cake and need to divide it by one person. Ok: (2/pi)/1 = 2/pi, a whole cake. Here you go one person!

What about half a person? (2/pi)/0.5 = 4/pi or 2 wholes. Right? Wrong! You just go around once, and obviously the rest doesn't matter since you traced the whole, but for the sake of math we will trace a full circle again. The whole cake has been traced around anyway and the half person gets the full cake

What about a third of a person? Same you just go around and stop where you went around already, effectively making no difference.

What about Infinity? Same no difference. Whole cake.

Does this work for 2 people, you, a skeptical reader might be now wondering, now concerned about the nonsense I wrote. Well yes, idiot reader, it does work. Here is how: (2/pi)/2 = pi or half of a whole. So you give the traced amount to the first person and continue tracing (2/pi)/2 for the second person. Another half!

And so, quod erat demonstrandum

Edit: What happens if you try dividing by infinity:

my god
why would you have 2pi of a cake tho
Well assuming its a regular cylindrical cake
It should have 2pi*r^2*h of edible volume available.

3D is irrelevant when cutting the cake because of the subsection nature of the cut. If you have a 4D knife and cake on the other hand, then would play a role.

Why not?
This thread is a fathom away from plunging into the abyss of mathematics, I would like to execute a strategical retreat.
how did it get this complicated
I thought the answer was () (you divided the 0 in the middle and it splited into () )
Now that's what I call being tactful

How so? How would you even know what a 4D shape looks like? Let alone cut it. The motion of cutting implies 3D. How do you cut a 2D cake with a 2D knife without going to the 3rd Dimension?? (Slicing doesn't count)
Plus, what does a 4D cake even look like?? A 2D cake is pi*r^2, a 3D cake is pi*r^2*h, but the 2 shapes are different. The equivalent of a circle in 3D is a sphere, not some puny cylinder. Note: we can consider a cylinder as 2-2D objects: circles and a rectangle. So what is the combination for a 4D cake??
Cylinder + rectangular prism??(which is the equivalent of 2*circle*rectangle + rectangle*6 in 2D world). Cylinder + Sphere?

Why not?
First off, it's 2pi radians of a cake. Things need units depending on what you're measuring. For example, when measuring your dick, you would say x dx long. Now if you don't know what radians are, you obviously haven't played enough MMORPG to know what raids are, which means you should go play more. Now since I'm a nice person, I'll explain what radians are. It's basically a unit that we use to see whether we hit the G spot or not
because god say it can't

First if you cut a 2D cake with a 2D knife, then your are effectively squashing it and not cutting it, because you know, like you said how would that go to the 3rd Dimension? It would make more sense to cut a 1D cake with a 2D knife. A 4D cake is impossible for a 3D being to comprehend, but it would would be a 4D cylinder. Here is a 4D cylinder being rotated in a crossection of 3D space:
