We look at the division of 97166399 by 571 
We're looking to find how many times 571 goes into 97166399.

On to step 1:
9 divided by 571 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 571

Moving on to step 2:
The number 571 fits into 97 0 times, leaving a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Take the next digit (1) from the dividend and append it to 97, then repeat: 971 / 571

Going ahead to step 3:
571 can be fit into 971 1 times, resulting in a remainder of 400.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 400 after subtracting 571 from 971.
Include the next digit (6) from the dividend after 400, then repeat: 4006 / 571

Step 4:
The number 571 fits into 4006 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 3997 from 4006 and we're left with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 571

Advancing to step 5:
If we divide 96 by 571, we get 0 and a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 170.0
The remainder is 96 after subtracting 0 from 96.
Fetch the next digit (3) from the dividend, attach it to 96 and continue: 963 / 571

On to step 6:
963 divided by 571 is 1 with a remainder of 392.
The number 1 becomes the next digit in our result. 
Result so far: 1701.0
Subtract 571 from 963 to get 392.
Include the next digit (9) from the dividend after 392, then repeat: 3929 / 571

Step 7:
571 goes into 3929 6 times with a remainder of 503.
The next digit of our result is 6. 
Result so far: 17016.0
If we take 3426 away from 3929, we end up with 503.
Append the next digit (9) from the dividend to 503 and continue with: 5039 / 571

Step 8:
571 can be fit into 5039 8 times, resulting in a remainder of 471.
The next digit of our result is 8. 
Result so far: 170168.0
If we take 4568 away from 5039, we end up with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Going ahead to step 9:
If we divide 4710 by 571, we get 8 and a remainder of 142.
Put 8 as the next digit of the answer. 
Result so far: 170168.8
The remainder is 142 after subtracting 4568 from 4710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 10:
1420 divided by 571 is 2 with a remainder of 278.
The next digit of our result is 2. 
Result so far: 170168.82
Subtract 1142 from 1420 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 11:
2780 divided by 571 is 4 with a remainder of 496.
Record the quotient 4 as the next digit in the result. 
Result so far: 170168.824
If we subtract 2284 from 2780, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 12:
571 can be fit into 4960 8 times, resulting in a remainder of 392.
Record the quotient 8 as the next digit in the result. 
Result so far: 170168.8248
If we subtract 4568 from 4960, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 13:
571 can be fit into 3920 6 times, resulting in a remainder of 494.
Use 6 as the next digit of our solution. 
Result so far: 170168.82486
If we take 3426 away from 3920, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 14:
When dividing 4940 by 571, we get 8 with a remainder of 372.
Put 8 as the next digit of the answer. 
Result so far: 170168.824868
Subtract 4568 from 4940 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 15:
If we divide 3720 by 571, we get 6 and a remainder of 294.
Use 6 as the next digit of our solution. 
Result so far: 170168.8248686
The remainder is 294 after subtracting 3426 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 16:
571 goes into 2940 5 times with a remainder of 85.
The next digit of our result is 5. 
Result so far: 170168.82486865
Subtracting 2855 from 2940 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

In conclusion, the division gives 170168.82486865 with a balance of 8.5e-08.
