Do you really need the level of resolution afforded by dividing to 5V? Can you divide down to something like 0.5V instead? If so, you could use a 1meg in series with 1K. Current draw would only be about 1/2mA, and dissipation in the 1meg only 0.25W. Four 250k resistors in series would ensure that their individual voltage rating isn't exceeded.
