We look at the division of 85412585 by 517 
The aim is to understand the frequency of 517 in 85412585.

Let's proceed to step 1:
8 divided by 517 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 517

Going ahead to step 2:
When dividing 85 by 517, we get 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (4) from the dividend and append it to 85, then repeat: 854 / 517

Let's proceed to step 3:
517 goes into 854 1 times with a remainder of 337.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 517 from 854 to get 337.
Take the next digit (1) from the dividend and append it to 337, then repeat: 3371 / 517

On to step 4:
3371 divided by 517 is 6 with a remainder of 269.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 3102 away from 3371, we end up with 269.
Fetch the next digit (2) from the dividend, attach it to 269 and continue: 2692 / 517

Step 5:
If we divide 2692 by 517, we get 5 and a remainder of 107.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
The remainder is 107 after subtracting 2585 from 2692.
Fetch the next digit (5) from the dividend, attach it to 107 and continue: 1075 / 517

On to step 6:
The number 517 fits into 1075 2 times, leaving a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 1652.0
The remainder is 41 after subtracting 1034 from 1075.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 517

Going ahead to step 7:
The number 517 fits into 418 0 times, leaving a remainder of 418.
Record the quotient 0 as the next digit in the result. 
Result so far: 16520.0
If we subtract 0 from 418, we get 418.
Fetch the next digit (5) from the dividend, attach it to 418 and continue: 4185 / 517

Step 8:
517 goes into 4185 8 times with a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 165208.0
Subtract 4136 from 4185 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
If we divide 490 by 517, we get 0 and a remainder of 490.
Write down 0 as next digit of the result. 
Result so far: 165208.0
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 10:
When dividing 4900 by 517, we get 9 with a remainder of 247.
The number 9 becomes the next digit in our result. 
Result so far: 165208.09
Deduct 4653 from 4900 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 11:
If we divide 2470 by 517, we get 4 and a remainder of 402.
Put 4 as the next digit of the answer. 
Result so far: 165208.094
The remainder is 402 after subtracting 2068 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 12:
When dividing 4020 by 517, we get 7 with a remainder of 401.
Record the quotient 7 as the next digit in the result. 
Result so far: 165208.0947
If we take 3619 away from 4020, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Step 13:
4010 divided by 517 is 7 with a remainder of 391.
The number 7 becomes the next digit in our result. 
Result so far: 165208.09477
Deduct 3619 from 4010 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

In conclusion, the division gives 165208.09477 with a balance of 0.000391.
