12224017 divided by 864 
Let's see how many times 864 fits into 12224017.

On to step 1:
The number 864 fits into 1 0 times, leaving 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.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 864

Let's proceed to step 2:
When dividing 12 by 864, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 864

Step 3:
If we divide 122 by 864, we get 0 and a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 122 after subtracting 0 from 122.
Take the next digit (2) from the dividend and append it to 122, then repeat: 1222 / 864

Step 4:
If we divide 1222 by 864, we get 1 and a remainder of 358.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 864 from 1222, we get 358.
Take the next digit (4) from the dividend and append it to 358, then repeat: 3584 / 864

Going ahead to step 5:
3584 divided by 864 is 4 with a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 3456 from 3584 and we're left with 128.
Include the next digit (0) from the dividend after 128, then repeat: 1280 / 864

On to step 6:
If we divide 1280 by 864, we get 1 and a remainder of 416.
Use 1 as the next digit of our solution. 
Result so far: 141.0
The remainder is 416 after subtracting 864 from 1280.
Grab the next digit (1) from the dividend, add it to 416, then carry on: 4161 / 864

Moving on to step 7:
864 can be fit into 4161 4 times, resulting in a remainder of 705.
The number 4 becomes the next digit in our result. 
Result so far: 1414.0
If we subtract 3456 from 4161, we get 705.
Bring next digit (7) of the dividend behind the 705 and repeat the process: 7057 / 864

Moving on to step 8:
When dividing 7057 by 864, we get 8 with a remainder of 145.
The number 8 becomes the next digit in our result. 
Result so far: 14148.0
The remainder is 145 after subtracting 6912 from 7057.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 9:
If we divide 1450 by 864, we get 1 and a remainder of 586.
Use 1 as the next digit of our solution. 
Result so far: 14148.1
If we take 864 away from 1450, we end up with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Advancing to step 10:
5860 divided by 864 is 6 with a remainder of 676.
The number 6 becomes the next digit in our result. 
Result so far: 14148.16
Deduct 5184 from 5860 and we're left with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Moving on to step 11:
864 goes into 6760 7 times with a remainder of 712.
Write down 7 as next digit of the result. 
Result so far: 14148.167
If we subtract 6048 from 6760, we get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Advancing to step 12:
7120 divided by 864 is 8 with a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 14148.1678
Subtracting 6912 from 7120 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 13:
The number 864 fits into 2080 2 times, leaving a remainder of 352.
Put 2 as the next digit of the answer. 
Result so far: 14148.16782
The remainder is 352 after subtracting 1728 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 14:
The number 864 fits into 3520 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 14148.167824
Subtracting 3456 from 3520 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
640 divided by 864 is 0 with a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 14148.167824
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 16:
864 goes into 6400 7 times with a remainder of 352.
The next digit of our result is 7. 
Result so far: 14148.16782407
If we take 6048 away from 6400, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final outcome is 14148.16782407, with a leftover of 3.52e-07.
