 		 #30120 - RE: Voltage dividing
We'll it's for a voltage reference for an LM311 voltage comparator.

If you are looking for any precision, just dividing Vcc is not a good idea. Vcc will have a tolerance (see regulator data sheet)and some noise and the resistors have a tolerance. If ANY precision is required, use a voltage reference chip (look at www.maxim-ic.com).
