We look at the division of 564580 by 66 
We want to divide 564580 by 66.

On to step 1:
66 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 66

Going ahead to step 2:
66 goes into 56 0 times with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Append the next digit (4) from the dividend to 56 and continue with: 564 / 66

Advancing to step 3:
If we divide 564 by 66, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 36 after subtracting 528 from 564.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 66

Step 4:
If we divide 365 by 66, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we take 330 away from 365, we end up with 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 66

Moving on to step 5:
66 goes into 358 5 times with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 855.0
Subtract 330 from 358 to get 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 66

On to step 6:
If we divide 280 by 66, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 8554.0
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
If we divide 160 by 66, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 8554.2
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 8554.24
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
66 goes into 160 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 8554.242
The remainder is 28 after subtracting 132 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 8554.2424
Subtracting 264 from 280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
160 divided by 66 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 8554.24242
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
If we divide 280 by 66, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 8554.242424
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
The number 66 fits into 160 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 8554.2424242
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
If we divide 280 by 66, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 8554.24242424
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 8554.24242424, with a leftover of 1.6e-08.
