MIPS Bad Address in data stack

I'm just starting out in MIPS. I have an assignment as follows:

Count the number of multiples of X in a given array of 8 non-negative numbers, where X is a user chosen power-of-two value, e.g. 1, 2, 4, 8, ….

Write the necessary code to:

a. Read user input value, X. You can assume X is always a power-of-two integer, i.e. there is no need to check for invalid user input.

b. Count the number of multiples of X in arrayA and print the result on screen.

For this set of input given in the code, I'm trying to get my output to be

2
3

However, I have the following error: "Bad address in data/stack read: 0x00000090"

I'm using QTSpim simulator and this is the data segment information. May I know how is 0x00000090 not the memory location of the first element of the array I'm trying to access? This code may not achieve the desired output because I'm stuck at this stage of debugging.
