macro to populate value based on difference of dates

please help me to right a macro where differene of two dates will be months and that month will use to divide the no of days in second sheet and than those divided days will fill in cells from start date and ends with end date - eg

Sheet one - Start date - 01/01/2014, end date - 01/02/2014

Sheet two - no of days - 20

Sheet three - Months are in columsn from Jan'14 - Dec'14

Results - there are two months so 20/2 - 10 and value will enter 10 in Jan and 10 in Feb.... where its on month - it will be one entery.

Please suggest

Hi
I manage to creae the template and steps, please find attached and need urgent help

Hi,
Mnay thanks for your reply, please find attached the file with data.

Sorry but this is not what i wanted, i want results in tab 'res' if you can see steps defined in fist tab, and results defined in last tab, i am sure you will be anble to understand.
Value should be auto placed in last jab under months column based on start and e nd date defined in first tab.. for ex if start date is 01/01/2014 and end date is 01/03/2014... and value against same date in tab two is 20 days... then 20 days will be devided with the difference of dates, which is two months means it will be 20/2 =10 and this 10 value will be than go to last tab under Jan and Feb that means 10 in Jan and 10 in feb... because from date start date, its jan and feb..
