We look at the division of 66628604 by 571 
We want to divide 66628604 by 571.

Moving on to step 1:
6 divided by 571 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 571

Going ahead to step 2:
If we divide 66 by 571, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 571

Let's proceed to step 3:
666 divided by 571 is 1 with a remainder of 95.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 571 from 666 leaves us with 95.
Bring next digit (2) of the dividend behind the 95 and repeat the process: 952 / 571

Moving on to step 4:
571 goes into 952 1 times with a remainder of 381.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 571 away from 952, we end up with 381.
Include the next digit (8) from the dividend after 381, then repeat: 3818 / 571

On to step 5:
571 goes into 3818 6 times with a remainder of 392.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
If we subtract 3426 from 3818, we get 392.
Bring next digit (6) of the dividend behind the 392 and repeat the process: 3926 / 571

On to step 6:
If we divide 3926 by 571, we get 6 and a remainder of 500.
The next digit of our result is 6. 
Result so far: 1166.0
If we subtract 3426 from 3926, we get 500.
Bring next digit (0) of the dividend behind the 500 and repeat the process: 5000 / 571

On to step 7:
5000 divided by 571 is 8 with a remainder of 432.
Write down 8 as next digit of the result. 
Result so far: 11668.0
The remainder is 432 after subtracting 4568 from 5000.
Fetch the next digit (4) from the dividend, attach it to 432 and continue: 4324 / 571

Advancing to step 8:
If we divide 4324 by 571, we get 7 and a remainder of 327.
Use 7 as the next digit of our solution. 
Result so far: 116687.0
The remainder is 327 after subtracting 3997 from 4324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 9:
The number 571 fits into 3270 5 times, leaving a remainder of 415.
Use 5 as the next digit of our solution. 
Result so far: 116687.5
Deduct 2855 from 3270 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 10:
571 can be fit into 4150 7 times, resulting in a remainder of 153.
Use 7 as the next digit of our solution. 
Result so far: 116687.57
If we take 3997 away from 4150, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 11:
1530 divided by 571 is 2 with a remainder of 388.
The number 2 becomes the next digit in our result. 
Result so far: 116687.572
Subtracting 1142 from 1530 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 12:
571 can be fit into 3880 6 times, resulting in a remainder of 454.
The next digit of our result is 6. 
Result so far: 116687.5726
Deduct 3426 from 3880 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 13:
4540 divided by 571 is 7 with a remainder of 543.
Use 7 as the next digit of our solution. 
Result so far: 116687.57267
Subtracting 3997 from 4540 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Going ahead to step 14:
571 goes into 5430 9 times with a remainder of 291.
The number 9 becomes the next digit in our result. 
Result so far: 116687.572679
Deduct 5139 from 5430 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 15:
If we divide 2910 by 571, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 116687.5726795
Deduct 2855 from 2910 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 16:
If we divide 550 by 571, we get 0 and a remainder of 550.
Use 0 as the next digit of our solution. 
Result so far: 116687.5726795
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Our division results in 116687.5726795 with a remaining 5.5e-07.
