Excel Programming help need to find multiple averages and sums

Hey,

I am new to excel and need help creating a macro to do a simple task.

First, I would like excel to take the sum of the cells in B2:B1441 and place that sum in cell J2
I would like it to then take the sum of the cells in B1442:B2881 and place that sum in cell J3
And continue this trend up until we take the sum of B420542:B421981 and place that in cell J294

Following that, I would like to do the same thing for column C
For example, take the sum of the cells in C2:C1441 and place that sum in cell K2
Up until the point where the sum of cells C420542:C421981 and place that in cell K294

I would like to repeat that for columns up until column G
Where for example the sum of the cells G2:G1441 would be placed in Cell O2
Up until the point where the sum of cells G420542:G421981 and place that in cell O294


After that, I would like to do the same function, but taking the averages of the columns instead of the sums.

For example, I would take the average of cells B2:B1441 and place that in cell R2
And continue this trend up until we take the average of B420542:B421981 and place that in cell R294

I would like to continue this trend for the same columns (B-G) placing them in the corresponding cells
For example, I would continue until we take the average of G2:G1441 would be placed in Cell W2
Up until we take the average of cells G420542:G421981 and place that in cell W294

Thank you so much. Help is very much appreciated
