{{blockquote|There is nobody who isn't surprised of the small price of [[pin]]s; but we shall be even more surprised, when we know how many different operations, most of them very delicate, are mandatory to make a good pin. We are going to go through these operations in a few words to stimulate the curiosity to know their detail; this enumeration will supply as many articles which will make the division of this work.… The first operation is to have brass go through the drawing plate to calibrate it.…|title=|source=}}

By "division of this work," du Monceau is referring to the subdivisions of 
the text describing the various trades involved in the pin making activity; this can also be described as a division of labour.
