Why is there an error in the calculation of 366.0/5.0?
All computers make imperfect calculations. It's a fact of life with finite precision floating point math.

Is it possible to subtract the baseline of a graph from the peak using the curvefitter toolbox?
Yes, it would be possible, although for what you show it might be enough just to use polyfit.
