55876647 ÷ 561 
Our goal is to divide 55876647 by 561.

Let's proceed to step 1:
When dividing 5 by 561, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 561

Let's proceed to step 2:
When dividing 55 by 561, we get 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 561

Moving on to step 3:
The number 561 fits into 558 0 times, leaving a remainder of 558.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 558 and we're left with 558.
Fetch the next digit (7) from the dividend, attach it to 558 and continue: 5587 / 561

Going ahead to step 4:
561 can be fit into 5587 9 times, resulting in a remainder of 538.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 5049 from 5587 to get 538.
Grab the next digit (6) from the dividend, add it to 538, then carry on: 5386 / 561

Step 5:
561 goes into 5386 9 times with a remainder of 337.
The next digit of our result is 9. 
Result so far: 99.0
If we subtract 5049 from 5386, we get 337.
Fetch the next digit (6) from the dividend, attach it to 337 and continue: 3376 / 561

Step 6:
561 can be fit into 3376 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 996.0
Subtracting 3366 from 3376 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 561

On to step 7:
561 can be fit into 104 0 times, resulting in a remainder of 104.
Record the quotient 0 as the next digit in the result. 
Result so far: 9960.0
The remainder is 104 after subtracting 0 from 104.
Grab the next digit (7) from the dividend, add it to 104, then carry on: 1047 / 561

Going ahead to step 8:
561 goes into 1047 1 times with a remainder of 486.
Record the quotient 1 as the next digit in the result. 
Result so far: 99601.0
Deduct 561 from 1047 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Step 9:
4860 divided by 561 is 8 with a remainder of 372.
The number 8 becomes the next digit in our result. 
Result so far: 99601.8
Subtracting 4488 from 4860 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 10:
561 can be fit into 3720 6 times, resulting in a remainder of 354.
Use 6 as the next digit of our solution. 
Result so far: 99601.86
Subtracting 3366 from 3720 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 11:
When dividing 3540 by 561, we get 6 with a remainder of 174.
The number 6 becomes the next digit in our result. 
Result so far: 99601.866
If we subtract 3366 from 3540, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The final outcome is 99601.866, with a leftover of 0.0174.
