What follows the Main Engine Cutoff (MECO) of the first stage?

Answer

Separation, often assisted by explosive bolts or springs.

After the first stage expends most of its propellant and executes MECO, separation from the upper stage occurs. This separation is often aided by mechanisms like small explosive bolts or springs to ensure a clean break between the two sections.
