I never used "Defer" before, so this might be unnecessary complicated.
With a toy function as example:

Block[{Defer = HoldForm},
Composition[Evaluate, ToExpression, ToString, InputForm,
HoldForm[Int][(Sqrt[x] + 2 + x^2)/(x + Sqrt[2 + x^2]), x]]]]

this prints the applied rules and returns a list of the intermediate
results. If you want the result only, but the should print, change
"Most[FixedPointList[...]]" to "FixedPoint[...]"
