excel跨范围分配值

Question

i need a formula to distribute values across a range while accounting for the max value possible

conditions to check:

1. IF the cell value is less than max then take cell value, ELSE
2. subtract cell value from max AND
3. check conditions if there is a remainder in the subtraction and add to the next row; otherwise place 0

sample data & ideal outcome breakdown is the ideal outcome

i know VBA can solve this but i'd rather not if possible. thanks for any help.

Also, not against using a helper column :)

Updated

when the values are the same on the series, it replaces with a 0 any idea it can dynamically reset based on the length of the series

Answer 1

put this in B3 and copy down:

=IF(A3<>A2,MIN(A3,$B$1),MIN(A3-SUM(INDEX(B:B,MATCH(A3,A:A,0)):B2),$B$1))
