We look at the division of 66120496 by 571 
We're looking to find how many times 571 goes into 66120496.

Step 1:
571 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 571

Step 2:
If we divide 66 by 571, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 571

On to step 3:
If we divide 661 by 571, we get 1 and a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 571 from 661 leaves us with 90.
Take the next digit (2) from the dividend and append it to 90, then repeat: 902 / 571

Step 4:
571 can be fit into 902 1 times, resulting in a remainder of 331.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 571 away from 902, we end up with 331.
Grab the next digit (0) from the dividend, add it to 331, then carry on: 3310 / 571

Moving on to step 5:
3310 divided by 571 is 5 with a remainder of 455.
Write down 5 as next digit of the result. 
Result so far: 115.0
Subtract 2855 from 3310 to get 455.
Include the next digit (4) from the dividend after 455, then repeat: 4554 / 571

Moving on to step 6:
When dividing 4554 by 571, we get 7 with a remainder of 557.
Record the quotient 7 as the next digit in the result. 
Result so far: 1157.0
Deduct 3997 from 4554 and we're left with 557.
Fetch the next digit (9) from the dividend, attach it to 557 and continue: 5579 / 571

Advancing to step 7:
571 goes into 5579 9 times with a remainder of 440.
The number 9 becomes the next digit in our result. 
Result so far: 11579.0
Deduct 5139 from 5579 and we're left with 440.
Append the next digit (6) from the dividend to 440 and continue with: 4406 / 571

On to step 8:
If we divide 4406 by 571, we get 7 and a remainder of 409.
Put 7 as the next digit of the answer. 
Result so far: 115797.0
If we subtract 3997 from 4406, we get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Advancing to step 9:
The number 571 fits into 4090 7 times, leaving a remainder of 93.
Put 7 as the next digit of the answer. 
Result so far: 115797.7
Subtracting 3997 from 4090 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 10:
571 goes into 930 1 times with a remainder of 359.
The next digit of our result is 1. 
Result so far: 115797.71
Deduct 571 from 930 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

On to step 11:
The number 571 fits into 3590 6 times, leaving a remainder of 164.
The next digit of our result is 6. 
Result so far: 115797.716
Deduct 3426 from 3590 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 12:
If we divide 1640 by 571, we get 2 and a remainder of 498.
Write down 2 as next digit of the result. 
Result so far: 115797.7162
Subtracting 1142 from 1640 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 13:
The number 571 fits into 4980 8 times, leaving a remainder of 412.
Use 8 as the next digit of our solution. 
Result so far: 115797.71628
Subtracting 4568 from 4980 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 14:
The number 571 fits into 4120 7 times, leaving a remainder of 123.
The number 7 becomes the next digit in our result. 
Result so far: 115797.716287
If we subtract 3997 from 4120, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 15:
571 can be fit into 1230 2 times, resulting in a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 115797.7162872
Deduct 1142 from 1230 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 16:
880 divided by 571 is 1 with a remainder of 309.
Put 1 as the next digit of the answer. 
Result so far: 115797.71628721
Deduct 571 from 880 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

The quotient of the division is 115797.71628721, and the remainder is 3.09e-07.
