In a recent python-dev thread, there was some confusion about how to get something like `timedelta.total_microseconds()`. There is already an existing, supported idiom for this, which is that `timedelta` implements division:

    td = timedelta(hours=1)
    num_microseconds = td / timedelta(microseconds=1)

In this e-mail ( https://mail.python.org/pipermail/python-dev/2019-February/156351.html ), Nick Coghlan proposed that we update the documentation and there were no objections, quoting:

    * In the "Supported Operations" section of https://docs.python.org/3/library/datetime.html#timedelta-objects,
      change "Division (3) of t2 by t3." to "Division (3) of overall
      duration t2 by interval unit t3."
    * In the total_seconds() documentation, add a sentence "For interval units
      other than seconds, use the division form directly (e.g. `td / timedelta(microseconds=1)`)"


I am starting this issue to track that change.
