    Helper function. Creates a tuple of even dividends given
    a range of divisors.

    Inputs
      seconds - number of seconds to format
      *divisors - a number of integer dividends. The number of seconds will be
                  integer-divided by the first number in this sequence, the remainder
                  will be divided with the second and so on.
    Output:
        A tuple of length len(*args)+1, with the last element being the last remaining
        seconds not evenly divided by the supplied dividends.
