We look at the division of 54886425 by 863 
We want to divide 54886425 by 863.

Advancing to step 1:
The number 863 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 863

Going ahead to step 2:
863 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 863

Moving on to step 3:
548 divided by 863 is 0 with a remainder of 548.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 548, we end up with 548.
Append the next digit (8) from the dividend to 548 and continue with: 5488 / 863

Going ahead to step 4:
5488 divided by 863 is 6 with a remainder of 310.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 310 after subtracting 5178 from 5488.
Fetch the next digit (6) from the dividend, attach it to 310 and continue: 3106 / 863

Moving on to step 5:
3106 divided by 863 is 3 with a remainder of 517.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 2589 from 3106 to get 517.
Bring next digit (4) of the dividend behind the 517 and repeat the process: 5174 / 863

Moving on to step 6:
863 can be fit into 5174 5 times, resulting in a remainder of 859.
The next digit of our result is 5. 
Result so far: 635.0
The remainder is 859 after subtracting 4315 from 5174.
Include the next digit (2) from the dividend after 859, then repeat: 8592 / 863

Step 7:
863 can be fit into 8592 9 times, resulting in a remainder of 825.
The next digit of our result is 9. 
Result so far: 6359.0
Subtracting 7767 from 8592 leaves us with 825.
Append the next digit (5) from the dividend to 825 and continue with: 8255 / 863

Step 8:
When dividing 8255 by 863, we get 9 with a remainder of 488.
Write down 9 as next digit of the result. 
Result so far: 63599.0
If we subtract 7767 from 8255, we get 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 9:
863 can be fit into 4880 5 times, resulting in a remainder of 565.
Write down 5 as next digit of the result. 
Result so far: 63599.5
If we subtract 4315 from 4880, we get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Step 10:
863 can be fit into 5650 6 times, resulting in a remainder of 472.
The next digit of our result is 6. 
Result so far: 63599.56
The remainder is 472 after subtracting 5178 from 5650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 11:
If we divide 4720 by 863, we get 5 and a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 63599.565
The remainder is 405 after subtracting 4315 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 12:
863 can be fit into 4050 4 times, resulting in a remainder of 598.
Record the quotient 4 as the next digit in the result. 
Result so far: 63599.5654
The remainder is 598 after subtracting 3452 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 13:
863 goes into 5980 6 times with a remainder of 802.
The number 6 becomes the next digit in our result. 
Result so far: 63599.56546
Subtracting 5178 from 5980 leaves us with 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Advancing to step 14:
8020 divided by 863 is 9 with a remainder of 253.
Use 9 as the next digit of our solution. 
Result so far: 63599.565469
Subtract 7767 from 8020 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 15:
The number 863 fits into 2530 2 times, leaving a remainder of 804.
The next digit of our result is 2. 
Result so far: 63599.5654692
Subtract 1726 from 2530 to get 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Let's proceed to step 16:
The number 863 fits into 8040 9 times, leaving a remainder of 273.
Put 9 as the next digit of the answer. 
Result so far: 63599.56546929
If we take 7767 away from 8040, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

The final outcome is 63599.56546929, with a leftover of 2.73e-07.
