55280557 ÷ 647 
We want to figure out the number of times 55280557 can be divided by 647.

Moving on to step 1:
647 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 647

Step 2:
647 can be fit into 55 0 times, resulting in a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 647

Going ahead to step 3:
647 goes into 552 0 times with a remainder of 552.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 552, we end up with 552.
Grab the next digit (8) from the dividend, add it to 552, then carry on: 5528 / 647

Advancing to step 4:
647 can be fit into 5528 8 times, resulting in a remainder of 352.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 352 after subtracting 5176 from 5528.
Append the next digit (0) from the dividend to 352 and continue with: 3520 / 647

Step 5:
If we divide 3520 by 647, we get 5 and a remainder of 285.
The next digit of our result is 5. 
Result so far: 85.0
If we take 3235 away from 3520, we end up with 285.
Grab the next digit (5) from the dividend, add it to 285, then carry on: 2855 / 647

Step 6:
If we divide 2855 by 647, we get 4 and a remainder of 267.
Put 4 as the next digit of the answer. 
Result so far: 854.0
Deduct 2588 from 2855 and we're left with 267.
Include the next digit (5) from the dividend after 267, then repeat: 2675 / 647

Moving on to step 7:
If we divide 2675 by 647, we get 4 and a remainder of 87.
Put 4 as the next digit of the answer. 
Result so far: 8544.0
Subtract 2588 from 2675 to get 87.
Take the next digit (7) from the dividend and append it to 87, then repeat: 877 / 647

On to step 8:
The number 647 fits into 877 1 times, leaving a remainder of 230.
Put 1 as the next digit of the answer. 
Result so far: 85441.0
If we subtract 647 from 877, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 9:
2300 divided by 647 is 3 with a remainder of 359.
The number 3 becomes the next digit in our result. 
Result so far: 85441.3
Deduct 1941 from 2300 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Going ahead to step 10:
647 can be fit into 3590 5 times, resulting in a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 85441.35
Deduct 3235 from 3590 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 11:
3550 divided by 647 is 5 with a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 85441.355
The remainder is 315 after subtracting 3235 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The quotient of the division is 85441.355, and the remainder is 0.0315.
