We look at the division of 23339471 by 571 
The aim is to understand the frequency of 571 in 23339471.

Let's proceed to step 1:
2 divided by 571 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 571

On to step 2:
23 divided by 571 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 571

Moving on to step 3:
571 goes into 233 0 times with a remainder of 233.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 233, we end up with 233.
Fetch the next digit (3) from the dividend, attach it to 233 and continue: 2333 / 571

Let's proceed to step 4:
When dividing 2333 by 571, we get 4 with a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2284 from 2333, we get 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 571

Let's proceed to step 5:
If we divide 499 by 571, we get 0 and a remainder of 499.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 499 to get 499.
Include the next digit (4) from the dividend after 499, then repeat: 4994 / 571

Step 6:
4994 divided by 571 is 8 with a remainder of 426.
The next digit of our result is 8. 
Result so far: 408.0
Subtract 4568 from 4994 to get 426.
Include the next digit (7) from the dividend after 426, then repeat: 4267 / 571

On to step 7:
If we divide 4267 by 571, we get 7 and a remainder of 270.
Put 7 as the next digit of the answer. 
Result so far: 4087.0
If we take 3997 away from 4267, we end up with 270.
Include the next digit (1) from the dividend after 270, then repeat: 2701 / 571

Step 8:
571 goes into 2701 4 times with a remainder of 417.
Record the quotient 4 as the next digit in the result. 
Result so far: 40874.0
The remainder is 417 after subtracting 2284 from 2701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Step 9:
571 goes into 4170 7 times with a remainder of 173.
Write down 7 as next digit of the result. 
Result so far: 40874.7
Subtracting 3997 from 4170 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 10:
571 can be fit into 1730 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 40874.73
If we take 1713 away from 1730, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 11:
The number 571 fits into 170 0 times, leaving a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 40874.73
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 12:
When dividing 1700 by 571, we get 2 with a remainder of 558.
The next digit of our result is 2. 
Result so far: 40874.7302
The remainder is 558 after subtracting 1142 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 13:
When dividing 5580 by 571, we get 9 with a remainder of 441.
The next digit of our result is 9. 
Result so far: 40874.73029
Subtract 5139 from 5580 to get 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

On to step 14:
If we divide 4410 by 571, we get 7 and a remainder of 413.
Put 7 as the next digit of the answer. 
Result so far: 40874.730297
Subtract 3997 from 4410 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Advancing to step 15:
The number 571 fits into 4130 7 times, leaving a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 40874.7302977
If we take 3997 away from 4130, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

The final result is 40874.7302977 with a remainder of 1.33e-06.
