Question regarding details of an intern position

I worked at a boutique in the financial services industry as an intern. I performed an array of different tasks that were basically assisting senior colleagues and had some level of reponsibility with tasks, but never managed to produce any major achievements or results with my work.

Is it fine if for this position I've outlined my responsbilities and what I did in some sort of detail without achieving any major breakthroughs etc. since the nature of the work was to assist in on-going tasks and processes..?
