55664899 ÷ 728 
Our goal is to divide 55664899 by 728.

On to step 1:
When dividing 5 by 728, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 728

Let's proceed to step 2:
55 divided by 728 is 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 728

Going ahead to step 3:
728 goes into 556 0 times with a remainder of 556.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 556 after subtracting 0 from 556.
Take the next digit (6) from the dividend and append it to 556, then repeat: 5566 / 728

On to step 4:
The number 728 fits into 5566 7 times, leaving a remainder of 470.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 5096 from 5566 and we're left with 470.
Fetch the next digit (4) from the dividend, attach it to 470 and continue: 4704 / 728

Advancing to step 5:
The number 728 fits into 4704 6 times, leaving a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 4368 from 4704 to get 336.
Append the next digit (8) from the dividend to 336 and continue with: 3368 / 728

Going ahead to step 6:
728 goes into 3368 4 times with a remainder of 456.
Use 4 as the next digit of our solution. 
Result so far: 764.0
Subtracting 2912 from 3368 leaves us with 456.
Append the next digit (9) from the dividend to 456 and continue with: 4569 / 728

On to step 7:
728 can be fit into 4569 6 times, resulting in a remainder of 201.
Write down 6 as next digit of the result. 
Result so far: 7646.0
If we take 4368 away from 4569, we end up with 201.
Fetch the next digit (9) from the dividend, attach it to 201 and continue: 2019 / 728

On to step 8:
728 goes into 2019 2 times with a remainder of 563.
Write down 2 as next digit of the result. 
Result so far: 76462.0
Subtract 1456 from 2019 to get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Going ahead to step 9:
The number 728 fits into 5630 7 times, leaving a remainder of 534.
Put 7 as the next digit of the answer. 
Result so far: 76462.7
The remainder is 534 after subtracting 5096 from 5630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Let's proceed to step 10:
If we divide 5340 by 728, we get 7 and a remainder of 244.
Write down 7 as next digit of the result. 
Result so far: 76462.77
If we take 5096 away from 5340, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final outcome is 76462.77, with a leftover of 0.244.
