Division in indirect valuation

Hi all , I have an annual wagetype and i have to arrive at the monthly wagetype dividing it by 12 can we achieve this in indirect valuation?

for example anual basic is 100000 i have to reach at 8333.33 with the help of indirect valuation. I thought of 1/12 = 0.083 putting this as multiplication factor but we have only 2 decimal places there.so calculation goes wrong.

I hare read documentaion of INVAL but nowhere we have anything related to division .If anybody come across such a scenario please

guide me .
