We look at the division of 18825883 by 864 
Our goal is to divide 18825883 by 864.

Advancing to 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
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 864

Going ahead to step 2:
When dividing 18 by 864, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 864

Going ahead to step 3:
The number 864 fits into 188 0 times, leaving a remainder of 188.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 188 to get 188.
Bring next digit (2) of the dividend behind the 188 and repeat the process: 1882 / 864

On to step 4:
1882 divided by 864 is 2 with a remainder of 154.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 154 after subtracting 1728 from 1882.
Bring next digit (5) of the dividend behind the 154 and repeat the process: 1545 / 864

Step 5:
1545 divided by 864 is 1 with a remainder of 681.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 864 from 1545, we get 681.
Append the next digit (8) from the dividend to 681 and continue with: 6818 / 864

Going ahead to step 6:
864 can be fit into 6818 7 times, resulting in a remainder of 770.
The next digit of our result is 7. 
Result so far: 217.0
Subtracting 6048 from 6818 leaves us with 770.
Take the next digit (8) from the dividend and append it to 770, then repeat: 7708 / 864

Advancing to step 7:
When dividing 7708 by 864, we get 8 with a remainder of 796.
Put 8 as the next digit of the answer. 
Result so far: 2178.0
The remainder is 796 after subtracting 6912 from 7708.
Fetch the next digit (3) from the dividend, attach it to 796 and continue: 7963 / 864

Let's proceed to step 8:
If we divide 7963 by 864, we get 9 and a remainder of 187.
Write down 9 as next digit of the result. 
Result so far: 21789.0
Deduct 7776 from 7963 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 9:
When dividing 1870 by 864, we get 2 with a remainder of 142.
Record the quotient 2 as the next digit in the result. 
Result so far: 21789.2
Subtract 1728 from 1870 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 10:
1420 divided by 864 is 1 with a remainder of 556.
The next digit of our result is 1. 
Result so far: 21789.21
Subtract 864 from 1420 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 11:
864 can be fit into 5560 6 times, resulting in a remainder of 376.
The number 6 becomes the next digit in our result. 
Result so far: 21789.216
The remainder is 376 after subtracting 5184 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 12:
When dividing 3760 by 864, we get 4 with a remainder of 304.
Write down 4 as next digit of the result. 
Result so far: 21789.2164
If we subtract 3456 from 3760, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 13:
864 goes into 3040 3 times with a remainder of 448.
Record the quotient 3 as the next digit in the result. 
Result so far: 21789.21643
Subtract 2592 from 3040 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 14:
4480 divided by 864 is 5 with a remainder of 160.
Use 5 as the next digit of our solution. 
Result so far: 21789.216435
If we take 4320 away from 4480, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
864 can be fit into 1600 1 times, resulting in a remainder of 736.
The next digit of our result is 1. 
Result so far: 21789.2164351
If we subtract 864 from 1600, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Advancing to step 16:
The number 864 fits into 7360 8 times, leaving a remainder of 448.
Use 8 as the next digit of our solution. 
Result so far: 21789.21643518
The remainder is 448 after subtracting 6912 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

After the division, we end up with 21789.21643518 and a remainder of 4.48e-07.
