Description (last modified by )
sage: R.<x>=PowerSeriesRing(QQ, 'x') sage: (x+x^2).integral() 1/2*x^2 + 1/3*x^3 sage: R.<x,y>=PowerSeriesRing(QQ, 'x y') sage: (x+x^2).integral(x) ... AttributeError: 'MPowerSeries' object has no attribute 'integral'
I also implement division by a non unit series (thanks Nicolas for preliminary code) and fixes the latex method which was buggy

It seems that there is no conflict with #14334
2 remarks:
- there is a typo in quo_rem: increassing
- please use the new syntax ValueError?('please')

I have made a review patch. If you are happy with the few small changes I have made, you can set a positive review.

New review patch allows the denominator to lie in a different parent (as long as it coerces into that of the numerator), deals with an endless-loop bug, and adds doc and comments. If you are fine with it, Frederic and Florent, this is positive_review!
