Google Sheets: Split months into weeks

I have two columns. One column has months and the second one tokens.

I would like to split each month, e.g. Jan 2022 into the appropriate week numbers in a separate tab. E.g. January would feed a column with rows: Week 1 to Week 4, and February would continue on with Week 5 - Week 8.

Next to the weeks, I would like to divide the tokens evenly in another column. For example, April would have 4 weeks with 8,366,513 tokens / 4 (for each week)

I believe this can be done with ARRAYFORMULA reading column A, but I am not sure how to form it.
