We're dividing 10747585 by 864 
Let's see how many times 864 fits into 10747585.

Let's proceed to step 1:
The number 864 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 864

Moving on to step 2:
864 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 864

On to step 3:
864 can be fit into 107 0 times, resulting in a remainder of 107.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 107, we get 107.
Append the next digit (4) from the dividend to 107 and continue with: 1074 / 864

Moving on to step 4:
1074 divided by 864 is 1 with a remainder of 210.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 864 from 1074, we get 210.
Grab the next digit (7) from the dividend, add it to 210, then carry on: 2107 / 864

Advancing to step 5:
When dividing 2107 by 864, we get 2 with a remainder of 379.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 379 after subtracting 1728 from 2107.
Fetch the next digit (5) from the dividend, attach it to 379 and continue: 3795 / 864

Going ahead to step 6:
The number 864 fits into 3795 4 times, leaving a remainder of 339.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we take 3456 away from 3795, we end up with 339.
Bring next digit (8) of the dividend behind the 339 and repeat the process: 3398 / 864

Advancing to step 7:
864 can be fit into 3398 3 times, resulting in a remainder of 806.
Write down 3 as next digit of the result. 
Result so far: 1243.0
Subtract 2592 from 3398 to get 806.
Append the next digit (5) from the dividend to 806 and continue with: 8065 / 864

Going ahead to step 8:
The number 864 fits into 8065 9 times, leaving a remainder of 289.
Use 9 as the next digit of our solution. 
Result so far: 12439.0
If we take 7776 away from 8065, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 9:
864 goes into 2890 3 times with a remainder of 298.
Use 3 as the next digit of our solution. 
Result so far: 12439.3
Subtract 2592 from 2890 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 10:
2980 divided by 864 is 3 with a remainder of 388.
Record the quotient 3 as the next digit in the result. 
Result so far: 12439.33
Subtract 2592 from 2980 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final outcome is 12439.33, with a leftover of 0.388.
