Reasonable resistor values for voltage divider
This is not a voltage divider.

Since the applied voltage is between the two resistors the voltage at the top will be the applied voltage assuming nothing is attached to it.

You need to do it this way.

However, be aware, whatever is attatched where the meter is shown above will affect the voltage to some extent depending on it's resistance. However, I would not expect a typical multimeter to affect it, assuming you do not have it in current measuring mode.
