Let's divide 54104048 by 663
We want to divide 54104048 by 663.

Moving on to step 1:
663 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 663

Step 2:
54 divided by 663 is 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 663

Going ahead to step 3:
663 can be fit into 541 0 times, resulting in a remainder of 541.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 541, we end up with 541.
Take the next digit (0) from the dividend and append it to 541, then repeat: 5410 / 663

Let's proceed to step 4:
663 can be fit into 5410 8 times, resulting in a remainder of 106.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 5304 from 5410 to get 106.
Include the next digit (4) from the dividend after 106, then repeat: 1064 / 663

Going ahead to step 5:
When dividing 1064 by 663, we get 1 with a remainder of 401.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we subtract 663 from 1064, we get 401.
Include the next digit (0) from the dividend after 401, then repeat: 4010 / 663

On to step 6:
If we divide 4010 by 663, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 816.0
If we subtract 3978 from 4010, we get 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 663

Moving on to step 7:
The number 663 fits into 324 0 times, leaving a remainder of 324.
The next digit of our result is 0. 
Result so far: 8160.0
Deduct 0 from 324 and we're left with 324.
Take the next digit (8) from the dividend and append it to 324, then repeat: 3248 / 663

Advancing to step 8:
When dividing 3248 by 663, we get 4 with a remainder of 596.
Record the quotient 4 as the next digit in the result. 
Result so far: 81604.0
Subtract 2652 from 3248 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 9:
5960 divided by 663 is 8 with a remainder of 656.
The next digit of our result is 8. 
Result so far: 81604.8
Subtracting 5304 from 5960 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 10:
When dividing 6560 by 663, we get 9 with a remainder of 593.
The next digit of our result is 9. 
Result so far: 81604.89
Subtract 5967 from 6560 to get 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

On to step 11:
The number 663 fits into 5930 8 times, leaving a remainder of 626.
Put 8 as the next digit of the answer. 
Result so far: 81604.898
If we take 5304 away from 5930, we end up with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 12:
6260 divided by 663 is 9 with a remainder of 293.
The number 9 becomes the next digit in our result. 
Result so far: 81604.8989
Subtracting 5967 from 6260 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Advancing to step 13:
2930 divided by 663 is 4 with a remainder of 278.
The number 4 becomes the next digit in our result. 
Result so far: 81604.89894
If we subtract 2652 from 2930, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Let's proceed to step 14:
663 goes into 2780 4 times with a remainder of 128.
The next digit of our result is 4. 
Result so far: 81604.898944
Subtract 2652 from 2780 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 81604.898944, with a leftover of 1.28e-05.
