Technically speaking, it doesn't. It describes the likelihood (probability) of finding the electron in a given small volume of space. However, it doesn't say anything about the actual location, because one of the results of quantum mechanics is that you cannot uniquely specify the location of an electron.
Electrons travel in circular orbits around the nucleus-similar in structure to the solar system, but with electrostatic forces providing attraction, rather than gravity.

The Bohr Model, and its the basis of quantum theory
Protons and neutrons are always found in the nucleus of an atom. Scientists over the years have speculated the position of electrons. The currently accepted model is the Atomic Orbital Model. This model predicts that electrons are found in sub-orbitals which are positioned in subshells. These subshells are located between principle energy levels.
Electrons
The Quantum Mechanical model of the atom states that the location of the electrons around the atom cannot be precisely determined. The region where the electron can probably be found is known as the electron cloud.

Rotating around the nucleus.
They orbit around the nucleas of an atom, except in hydrogen atoms, which does not contain electrons at all.
How are electrons arranged in the quantum mechanical model of an atom
In this model, the electrons move or orbit around the protons that are at the center of the atom. Electrons move around the nucleus, which contains the proton, in orbits that have a definite size and energy.

It is made up of protons, neutrons, and electrons. The protons and neutrons are found in the nucleus of the atom, while the electrons are found moving around the outside of the nucleus. This is known as the "electron cloud" since the electrons move around randomly. The most current atom model is the Quantum Mechanical Model, if this helps.
