[issue15815] Add numerator to ZeroDivisionError messages

[Terry J. Reedy]

Terry J. Reedy added the comment:

In case the value of the numerator helps find out why the denominator is 0. The example given by Mike Graham on python-ideas, Verbose traceback formatting was

def f(a):
    x = a * 4
    y = a - 4
    return x / y
