Let's divide 86965076 by 571
The aim is to understand the frequency of 571 in 86965076.

Going ahead to step 1:
When dividing 8 by 571, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 571

Moving on to step 2:
86 divided by 571 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (9) from the dividend, attach it to 86 and continue: 869 / 571

Let's proceed to step 3:
571 can be fit into 869 1 times, resulting in a remainder of 298.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 571 from 869 and we're left with 298.
Include the next digit (6) from the dividend after 298, then repeat: 2986 / 571

Let's proceed to step 4:
When dividing 2986 by 571, we get 5 with a remainder of 131.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 2855 from 2986 to get 131.
Include the next digit (5) from the dividend after 131, then repeat: 1315 / 571

Going ahead to step 5:
If we divide 1315 by 571, we get 2 and a remainder of 173.
Put 2 as the next digit of the answer. 
Result so far: 152.0
If we subtract 1142 from 1315, we get 173.
Include the next digit (0) from the dividend after 173, then repeat: 1730 / 571

On to step 6:
When dividing 1730 by 571, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 1523.0
Subtract 1713 from 1730 to get 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 571

Let's proceed to step 7:
571 goes into 177 0 times with a remainder of 177.
The number 0 becomes the next digit in our result. 
Result so far: 15230.0
The remainder is 177 after subtracting 0 from 177.
Take the next digit (6) from the dividend and append it to 177, then repeat: 1776 / 571

Going ahead to step 8:
1776 divided by 571 is 3 with a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 152303.0
If we take 1713 away from 1776, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 9:
630 divided by 571 is 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 152303.1
Subtracting 571 from 630 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 10:
571 goes into 590 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 152303.11
If we subtract 571 from 590, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 152303.11 and a remainder of 0.019.
