We look at the division of 10097904 by 864 
Let's see how many times 864 fits into 10097904.

Step 1:
When dividing 1 by 864, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 864

On to step 2:
The number 864 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 864

Step 3:
864 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 100 after subtracting 0 from 100.
Append the next digit (9) from the dividend to 100 and continue with: 1009 / 864

Step 4:
When dividing 1009 by 864, we get 1 with a remainder of 145.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 145 after subtracting 864 from 1009.
Grab the next digit (7) from the dividend, add it to 145, then carry on: 1457 / 864

On to step 5:
864 can be fit into 1457 1 times, resulting in a remainder of 593.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 864 away from 1457, we end up with 593.
Include the next digit (9) from the dividend after 593, then repeat: 5939 / 864

Advancing to step 6:
The number 864 fits into 5939 6 times, leaving a remainder of 755.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
If we take 5184 away from 5939, we end up with 755.
Include the next digit (0) from the dividend after 755, then repeat: 7550 / 864

Moving on to step 7:
864 goes into 7550 8 times with a remainder of 638.
The number 8 becomes the next digit in our result. 
Result so far: 1168.0
Deduct 6912 from 7550 and we're left with 638.
Fetch the next digit (4) from the dividend, attach it to 638 and continue: 6384 / 864

Let's proceed to step 8:
When dividing 6384 by 864, we get 7 with a remainder of 336.
Use 7 as the next digit of our solution. 
Result so far: 11687.0
The remainder is 336 after subtracting 6048 from 6384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 9:
3360 divided by 864 is 3 with a remainder of 768.
The next digit of our result is 3. 
Result so far: 11687.3
Subtract 2592 from 3360 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Advancing to step 10:
The number 864 fits into 7680 8 times, leaving a remainder of 768.
Use 8 as the next digit of our solution. 
Result so far: 11687.38
Subtracting 6912 from 7680 leaves us with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Going ahead to step 11:
If we divide 7680 by 864, we get 8 and a remainder of 768.
Record the quotient 8 as the next digit in the result. 
Result so far: 11687.388
If we subtract 6912 from 7680, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

In conclusion, the division gives 11687.388 with a balance of 0.0768.
