2 problems, complicated copying of data based on a “Number” and dates

The first problem I have is that I have a timestamp in one cell which includes the date and time and I would like to know if there is any automated way to separate them into 2 different columns (Date and time).

The other problem is a bit complicated and pardon me for explaining this issue poorly. I have 2 worksheets to work with one includes the data. I would like to copy the “Activity” in sheet A (the one with data) to sheet B based on the date and the number.

Sheet A

This is my sheet A with the data.

Sheet B

This is sheet B that I need to work with. So as you can see the dates on sheet A is in rows and sheet B in columns. So I would like to input the data of “Activity” based on the “Number” (in this example 20981) and put in the correspondent date. I have been typing the data manually and I have over 8000 rows to go through so please help if there is a more automated way of working.
