Thanks. Anyway, one of my colleague have explained me the division in
the meantime :) In fact, despite you can easily split an addition or a
multiplication into several multiplications/additions, it's not so easy
with divisions... I will have to do it completely 'by hand', or find
wome workaround to have good looking results...
