Copy a formula x times sideways based on value in a cell

Hi guys, im not an expert on Excel and i been breaking my head over this , i have the attached workbook, where i have an amount and a formula dividing this amount into payments based on the number in column C ( the original workbook has same but in different Cells but concept is the same ).

Is there a way to copy and paste this formula sideways automatically based in the same number on cell C without doing manually.

Lets say if cell C is 10 payments then copy the formula 10 times starting in column # in the same row but also the formula use this number to divide the amount of the payments.

I dont know if i explained it correctly. Thanks for the help in advance.
