DAX Calculation (Running Total / Total ) - Help needed!

Hi, 

Context:

I have three tables below: 

Table 1: Is a simple count per batch number over the x axis (0,1,2,3,4 etc.)

Table 2: Is the running total

Table 3: Is the total per batch number

* EDIT: The running total's do not match table 3 because I have filtered out blanks

I would like to create a measure that will divide the running total by the total per batch. So I can create a table that will look like this:

Any suggestions?
