Frequently uncountable when describing the general process ('Insertion of the data takes seconds'). Countable when one specific act is meant ('three separate insertions were needed'). More common in formal, medical, or technical writing than in everyday speech, where the gerund 'inserting' or the verb 'put in' is preferred.
