  There is a lot of good information here www.emesystems.com/BS2index.htm#math
  But you will find that hobby servos will not give you the precision you seem to be expecting. I would recommend you investigate encoders if you need to stay with servos or perhaps stepper motors.

  Division can be inverted to become multiplication, so x / 6.92 = x * 0.145.
  
  Say you want to move 47 degrees. Then the variable would be 47 * 0.145, or on the Stamp,
  

  index = degrees ** 9471
  FOR counter = 1 to index
  ' ...
  

  
  
  As Stephen pointed out, the precision is not good. Maybe there is something mechanical that can make the steps smaller, say, by running the servos at 800 instead of 850.

  The end value can be a variable
  
  See Help for "FOR"
  
  FOR Counter = StartValue TO EndValue {STEP StepValue} ... NEXT
  
  
  EndValue is a variable/constant/expression* (0 - 65535) that specifies the end value of the variable (Counter). When the value of Counter is outside of the range StartValue to EndValue, the FOR...NEXT loop stops executing and the program goes on to the .....
