One way:

Assume the Goal per week value is in B1, number for Sunday in B2, etc.:

B2: =INT(B$1/6)
B3: =INT((B$1-SUM(B$2:B2))/(8-ROW()))

Copy down to B6.

Then in B7 (Friday) enter:

=B$1-SUM(B2:B6)

Using a spreadsheet I need a chart that would return the answer across the
rows.
Where the total is equal to the starting number. To answer how many lessons
can be taught each day to achieve the goal per week. My problem lies in that
I need whole numbers.
example
Goal per week 21
Sunday 8
Monday 4
Tuesday 3
Wednesday 2
Thursday 2
Friday 2

Total 21
