Math within an array

Hi! is there somebody that can help me with a VBA code for excel? Thanks in advance.
I have one column A with 100 values

Base=A(1)

i=i+1
B(i)=A(i)/Base Until B(i)>=1.1 Then Base=A(i)

Example
A B C First Base= 12
12
12.5 1.042 1
14.5 1.21 1,21 Second Base= 14,5
15 1.034 1
16 1.103 1.103 Third Base= 16

This procedure until I reach the last row occupied.
Best regards Alfredo
