The best online resistor/voltage divider calculator is at:

 

http://jansson.us/resistors.html

 

This will find parallel or series connections of standard resistor values to
produce a particular resistance or ratio.

 

TIP: The resistance ratio for a K:1 voltage divider is K - 1. For example,
the K value for a 35:5 divider is 7. The resistance ratio to enter into the
calculator is 6: (7 - 1)
