28797 ÷ 90 
We want to figure out the number of times 28797 can be divided by 90.

Moving on to step 1:
2 divided by 90 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 90

Step 2:
28 divided by 90 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 90

Advancing to step 3:
When dividing 287 by 90, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 270 from 287 and we're left with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 90

Step 4:
If we divide 179 by 90, we get 1 and a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 90 away from 179, we end up with 89.
Take the next digit (7) from the dividend and append it to 89, then repeat: 897 / 90

Moving on to step 5:
The number 90 fits into 897 9 times, leaving a remainder of 87.
The next digit of our result is 9. 
Result so far: 319.0
Subtract 810 from 897 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 6:
If we divide 870 by 90, we get 9 and a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 319.9
If we subtract 810 from 870, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
When dividing 600 by 90, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 319.96
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
If we divide 600 by 90, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 319.966
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 319.966 with a remainder of 0.006.
