568515 divided by 66 
Let's see how many times 66 fits into 568515.

On to step 1:
5 divided by 66 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 66

On to step 2:
56 divided by 66 is 0 with a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 66

Advancing to step 3:
The number 66 fits into 568 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 528 from 568 and we're left with 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 66

Going ahead to step 4:
405 divided by 66 is 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 396 away from 405, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 66

On to step 5:
The number 66 fits into 91 1 times, leaving a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 861.0
Subtracting 66 from 91 leaves us with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 66

Moving on to step 6:
If we divide 255 by 66, we get 3 and a remainder of 57.
The next digit of our result is 3. 
Result so far: 8613.0
If we take 198 away from 255, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 7:
66 can be fit into 570 8 times, resulting in a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 8613.8
Deduct 528 from 570 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
If we divide 420 by 66, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 8613.86
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
If we divide 240 by 66, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 8613.863
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
If we divide 420 by 66, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 8613.8636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
66 goes into 240 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 8613.86363
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
66 goes into 420 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 8613.863636
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 8613.8636363
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
420 divided by 66 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 8613.86363636
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 8613.86363636, with a leftover of 2.4e-08.
