Taking modulo works with Python float and Sage float:
sage: .45r % .28r
0.16999999999999998
sage: .45 % .28
-0.110000000000000
The quotient works with Python float:
sage: .45r // .28r
1.0
But why should it not work with Sage float as well?
sage: .45 // .28
Traceback (most recent call last):
...
TypeError: unsupported operand parent(s) for //: 'Real Field with 53 bits of precision' and 'Real Field with 53 bits of precision'
