#30154 - RE: back to Voltage dividing
"If I have a voltage divider using a 5V source and a 330K and a 100K resistor, then I get about 1.16v out of the other end.
"If I use a 33K and a 10K I also get 1.16v from the far end."


The key is in the name: "Voltage Divider"
A Voltage Divider divides the applied voltage in the same ratio as the resistor values; 330k:100k is the same ratio as 33k:10k, so you will get the same output voltage in both cases.
The only difference is the output impedance.

BTW: note that 'K' (uppercase) represents 2^10 = 1024, whereas 'k' (lowercase) represents 10^3 = 1000.
Hint: an easy way to remember this is that Big 'K' (1024) is greater than little 'k' (1000)
