28488621 ÷ 897 
We want to divide 28488621 by 897.

Moving on to step 1:
897 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 897

Step 2:
897 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 897

On to step 3:
284 divided by 897 is 0 with a remainder of 284.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 284, we get 284.
Append the next digit (8) from the dividend to 284 and continue with: 2848 / 897

Moving on to step 4:
897 goes into 2848 3 times with a remainder of 157.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 2691 from 2848 leaves us with 157.
Fetch the next digit (8) from the dividend, attach it to 157 and continue: 1578 / 897

Advancing to step 5:
1578 divided by 897 is 1 with a remainder of 681.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 897 from 1578 to get 681.
Grab the next digit (6) from the dividend, add it to 681, then carry on: 6816 / 897

Step 6:
897 can be fit into 6816 7 times, resulting in a remainder of 537.
Put 7 as the next digit of the answer. 
Result so far: 317.0
If we subtract 6279 from 6816, we get 537.
Bring next digit (2) of the dividend behind the 537 and repeat the process: 5372 / 897

On to step 7:
When dividing 5372 by 897, we get 5 with a remainder of 887.
Use 5 as the next digit of our solution. 
Result so far: 3175.0
Subtracting 4485 from 5372 leaves us with 887.
Fetch the next digit (1) from the dividend, attach it to 887 and continue: 8871 / 897

Step 8:
The number 897 fits into 8871 9 times, leaving a remainder of 798.
Record the quotient 9 as the next digit in the result. 
Result so far: 31759.0
Subtract 8073 from 8871 to get 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Let's proceed to step 9:
7980 divided by 897 is 8 with a remainder of 804.
Write down 8 as next digit of the result. 
Result so far: 31759.8
Subtract 7176 from 7980 to get 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Advancing to step 10:
If we divide 8040 by 897, we get 8 and a remainder of 864.
The next digit of our result is 8. 
Result so far: 31759.88
Subtract 7176 from 8040 to get 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

In conclusion, the division gives 31759.88 with a balance of 0.864.
