10688186 ÷ 864 
We want to figure out the number of times 10688186 can be divided by 864.

Going ahead to step 1:
If we divide 1 by 864, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 864

On to step 2:
When dividing 10 by 864, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 864

Let's proceed to step 3:
106 divided by 864 is 0 with a remainder of 106.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 106 leaves us with 106.
Fetch the next digit (8) from the dividend, attach it to 106 and continue: 1068 / 864

Going ahead to step 4:
1068 divided by 864 is 1 with a remainder of 204.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 864 from 1068 and we're left with 204.
Fetch the next digit (8) from the dividend, attach it to 204 and continue: 2048 / 864

Let's proceed to step 5:
864 can be fit into 2048 2 times, resulting in a remainder of 320.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1728 from 2048 leaves us with 320.
Append the next digit (1) from the dividend to 320 and continue with: 3201 / 864

On to step 6:
3201 divided by 864 is 3 with a remainder of 609.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
If we take 2592 away from 3201, we end up with 609.
Include the next digit (8) from the dividend after 609, then repeat: 6098 / 864

Let's proceed to step 7:
864 can be fit into 6098 7 times, resulting in a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 1237.0
Deduct 6048 from 6098 and we're left with 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 864

On to step 8:
864 can be fit into 506 0 times, resulting in a remainder of 506.
The number 0 becomes the next digit in our result. 
Result so far: 12370.0
Deduct 0 from 506 and we're left with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Moving on to step 9:
When dividing 5060 by 864, we get 5 with a remainder of 740.
The next digit of our result is 5. 
Result so far: 12370.5
Subtracting 4320 from 5060 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 10:
The number 864 fits into 7400 8 times, leaving a remainder of 488.
Use 8 as the next digit of our solution. 
Result so far: 12370.58
Subtracting 6912 from 7400 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 11:
When dividing 4880 by 864, we get 5 with a remainder of 560.
Record the quotient 5 as the next digit in the result. 
Result so far: 12370.585
Deduct 4320 from 4880 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 12:
When dividing 5600 by 864, we get 6 with a remainder of 416.
Record the quotient 6 as the next digit in the result. 
Result so far: 12370.5856
Deduct 5184 from 5600 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 13:
864 goes into 4160 4 times with a remainder of 704.
Write down 4 as next digit of the result. 
Result so far: 12370.58564
If we take 3456 away from 4160, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Moving on to step 14:
If we divide 7040 by 864, we get 8 and a remainder of 128.
The next digit of our result is 8. 
Result so far: 12370.585648
Deduct 6912 from 7040 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 15:
1280 divided by 864 is 1 with a remainder of 416.
The number 1 becomes the next digit in our result. 
Result so far: 12370.5856481
The remainder is 416 after subtracting 864 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 16:
The number 864 fits into 4160 4 times, leaving a remainder of 704.
Record the quotient 4 as the next digit in the result. 
Result so far: 12370.58564814
If we subtract 3456 from 4160, we get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

In conclusion, the division gives 12370.58564814 with a balance of 7.04e-07.
