Examples for Series ops should be specific to each method.
The code example for [Series.divmod](https://pandas.pydata.org/pandas-docs/stable/generated/pandas.Series.divmod.html) uses `Series.add` and I'm not sure what this is supposed to convey.

In addition, "Equivalent to `series divmod other`" and "See also: `Series.None`" look strange to me.
