Nice Database GUI for Lots of Text
The data itself is a very simple data problem, and any modern database system will work just fine (though I recommend staying away from MS Access just because it's antiquated as a database system nowadays).
The actual problem you're trying to solve is a UI one, which you'll want to likely provide a rich text editor for the end users to type their instructions (ProcessDescription) into. This can be accomplished easily with any desktop or web application, which there are a multitude of rich text editors out there for (dependent on whichever front-end / back-end stack you choose). The rich text editor will usually store the formatting of the text with special code (most times HTML tags or something similar are used) behind the scenes from the end user, which will be completely digestible by your database without any special extra work needed to store it and recall it in the same format.
