The form of government that divides most of the power is federalism.

Explanation:

Federalism is a political doctrine that seeks that a political entity or organization is formed by organisms (states, associations, groups, unions, etc.) that are associated delegating some freedoms or own powers to a higher body, to whom the sovereignty belongs and that they maintain a certain autonomy, since some competences belong exclusively to them. In other words, it is a political system in which the functions of the government are divided among a group of associated States, first, which then delegate powers to a central federal state.
