We look at the division of 8818309 by 561 
Our goal is to divide 8818309 by 561.

Advancing to step 1:
When dividing 8 by 561, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 561

Advancing to step 2:
If we divide 88 by 561, we get 0 and a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Fetch the next digit (1) from the dividend, attach it to 88 and continue: 881 / 561

Step 3:
561 can be fit into 881 1 times, resulting in a remainder of 320.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 561 from 881 to get 320.
Append the next digit (8) from the dividend to 320 and continue with: 3208 / 561

Going ahead to step 4:
3208 divided by 561 is 5 with a remainder of 403.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 2805 from 3208 and we're left with 403.
Append the next digit (3) from the dividend to 403 and continue with: 4033 / 561

Advancing to step 5:
If we divide 4033 by 561, we get 7 and a remainder of 106.
The next digit of our result is 7. 
Result so far: 157.0
If we take 3927 away from 4033, we end up with 106.
Fetch the next digit (0) from the dividend, attach it to 106 and continue: 1060 / 561

Moving on to step 6:
When dividing 1060 by 561, we get 1 with a remainder of 499.
Put 1 as the next digit of the answer. 
Result so far: 1571.0
The remainder is 499 after subtracting 561 from 1060.
Bring next digit (9) of the dividend behind the 499 and repeat the process: 4999 / 561

Moving on to step 7:
4999 divided by 561 is 8 with a remainder of 511.
Write down 8 as next digit of the result. 
Result so far: 15718.0
If we take 4488 away from 4999, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Going ahead to step 8:
5110 divided by 561 is 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 15718.9
Subtract 5049 from 5110 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
The number 561 fits into 610 1 times, leaving a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 15718.91
The remainder is 49 after subtracting 561 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 10:
If we divide 490 by 561, we get 0 and a remainder of 490.
Write down 0 as next digit of the result. 
Result so far: 15718.91
If we take 0 away from 490, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 11:
If we divide 4900 by 561, we get 8 and a remainder of 412.
The next digit of our result is 8. 
Result so far: 15718.9108
The remainder is 412 after subtracting 4488 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 12:
When dividing 4120 by 561, we get 7 with a remainder of 193.
Record the quotient 7 as the next digit in the result. 
Result so far: 15718.91087
Subtract 3927 from 4120 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 13:
561 goes into 1930 3 times with a remainder of 247.
Write down 3 as next digit of the result. 
Result so far: 15718.910873
If we subtract 1683 from 1930, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 14:
2470 divided by 561 is 4 with a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 15718.9108734
If we subtract 2244 from 2470, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 15:
561 can be fit into 2260 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 15718.91087344
The remainder is 16 after subtracting 2244 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 15718.91087344 and a remainder of 1.6e-08.
