What is the electric displacement field for one electron?

I am teaching myself Maxwells equations for fun and this question may be gibberish but I would like to know know the explicit formula for D for a single elecron so I can practice my use of the divergence theorem and check the divergence is the charge density.

The Electric Displacement vector, D, will depend on the surrounding material. The formula for D is just the permittivity of the surrounding material multiplied by E (in S.I. units).
