We look at the division of 55178425 by 864 
We want to divide 55178425 by 864.

Advancing to step 1:
When dividing 5 by 864, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 864

Moving on to step 2:
55 divided by 864 is 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 864

Advancing to step 3:
864 goes into 551 0 times with a remainder of 551.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 551, we get 551.
Grab the next digit (7) from the dividend, add it to 551, then carry on: 5517 / 864

On to step 4:
When dividing 5517 by 864, we get 6 with a remainder of 333.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 5184 from 5517 and we're left with 333.
Bring next digit (8) of the dividend behind the 333 and repeat the process: 3338 / 864

Moving on to step 5:
864 goes into 3338 3 times with a remainder of 746.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we subtract 2592 from 3338, we get 746.
Fetch the next digit (4) from the dividend, attach it to 746 and continue: 7464 / 864

Let's proceed to step 6:
864 goes into 7464 8 times with a remainder of 552.
Use 8 as the next digit of our solution. 
Result so far: 638.0
If we take 6912 away from 7464, we end up with 552.
Take the next digit (2) from the dividend and append it to 552, then repeat: 5522 / 864

Moving on to step 7:
864 goes into 5522 6 times with a remainder of 338.
Put 6 as the next digit of the answer. 
Result so far: 6386.0
If we take 5184 away from 5522, we end up with 338.
Include the next digit (5) from the dividend after 338, then repeat: 3385 / 864

On to step 8:
When dividing 3385 by 864, we get 3 with a remainder of 793.
Record the quotient 3 as the next digit in the result. 
Result so far: 63863.0
The remainder is 793 after subtracting 2592 from 3385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

On to step 9:
7930 divided by 864 is 9 with a remainder of 154.
The number 9 becomes the next digit in our result. 
Result so far: 63863.9
Subtract 7776 from 7930 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 10:
864 goes into 1540 1 times with a remainder of 676.
Use 1 as the next digit of our solution. 
Result so far: 63863.91
Subtracting 864 from 1540 leaves us 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.

Let's proceed to step 11:
6760 divided by 864 is 7 with a remainder of 712.
The next digit of our result is 7. 
Result so far: 63863.917
The remainder is 712 after subtracting 6048 from 6760.
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:
When dividing 7120 by 864, we get 8 with a remainder of 208.
Put 8 as the next digit of the answer. 
Result so far: 63863.9178
If we take 6912 away from 7120, we end up 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.

On to step 13:
When dividing 2080 by 864, we get 2 with a remainder of 352.
Record the quotient 2 as the next digit in the result. 
Result so far: 63863.91782
Subtract 1728 from 2080 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 14:
When dividing 3520 by 864, we get 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 63863.917824
If we take 3456 away from 3520, we end up 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.

Let's proceed to step 15:
If we divide 640 by 864, we get 0 and a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 63863.917824
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.

Moving on to step 16:
864 can be fit into 6400 7 times, resulting in a remainder of 352.
Write down 7 as next digit of the result. 
Result so far: 63863.91782407
The remainder is 352 after subtracting 6048 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Our division results in 63863.91782407 with a remaining 3.52e-07.
