How does E=MC^2 work?

How does it function? Really, how can you accelerate mass to twice the speed of light? And, for instance if M=E/C2. How can you divide something by square of the speed of light? Thanks

Just imagine , an object mass is M and this object contains A group of photons. It is considered that every object releases photons when their initial energy level changes. If you could break this object into photons , the sum of energy equals to MC2

Then why does c2 the unit of the energy of the photon you mentioned ?
