 The most obvious approach, rather hard-coded to the example,
 would be:

            cpuMhz = float(cpuSpeed[6:]) / 10 ** 6 

 ... take a "slice" of the string, cpuSpeed, from character 
 seven (zero-based) to the end of the string (cpuSpeed[6:]) and
 try to convert it into a floating point number (with the float()
 function) and then divide that by the one million
