Infinity is a concept. Mathematicians can treat infinity as a number but it is not literally meant to be a real or natural number. An object can be said to be multiplied by an infinite number of times or one object can be divided into an infinite amount of smaller units.
If you want to "look at infinity" then look at a fractal. A fractal can be magnified indefinitely without losing its structure because a fractal can have infinite perimeters.
