I need to solve this equation.
3E 9 N / 1.25 E 19 C
I do not know what to do with the 9 and 19.

Exponents in the denomimator get subtracted from the exponents in the numerator.
3E 9 is a computer programmer's way of writing 3*10^9. We don't use that notation here.
3*10^9 N / 1.25*10^19 C = (3/1.25)*10^10 = 2.4*10^10 N/C (or Volts per meter)
N/C is a measure of electric field strength
