What about more program approach using VimL - but you need to use whole function for that. Just to get number (don't sure where you want insert those numbers):

navigate to line with your week date and:

:echo ceil(split(getline('.'), '\s\+')[1]/1500.0)
15.0

for 'feuillets' (in Poland it is called 'standardowy maszynopis' and has 1800 characters BTW)

:let a=split(getline('.'), '\s\+') | echo a[2]/a[3]
11

Note: here you will get full number which Vim will always round down.

getline('.') - read current line
split(getline('.'), '\s\+\) - split current line into numbers without any whitespace
ceil() - round upward
a[2], a[3] - operate on numbers
