Let's divide 8235996 by 517
The aim is to understand the frequency of 517 in 8235996.

Step 1:
When dividing 8 by 517, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 517

Step 2:
517 goes into 82 0 times with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Take the next digit (3) from the dividend and append it to 82, then repeat: 823 / 517

Let's proceed to step 3:
823 divided by 517 is 1 with a remainder of 306.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 517 from 823, we get 306.
Fetch the next digit (5) from the dividend, attach it to 306 and continue: 3065 / 517

Step 4:
517 goes into 3065 5 times with a remainder of 480.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 2585 from 3065, we get 480.
Append the next digit (9) from the dividend to 480 and continue with: 4809 / 517

Advancing to step 5:
517 can be fit into 4809 9 times, resulting in a remainder of 156.
Write down 9 as next digit of the result. 
Result so far: 159.0
Subtracting 4653 from 4809 leaves us with 156.
Append the next digit (9) from the dividend to 156 and continue with: 1569 / 517

Let's proceed to step 6:
If we divide 1569 by 517, we get 3 and a remainder of 18.
The next digit of our result is 3. 
Result so far: 1593.0
Deduct 1551 from 1569 and we're left with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 517

Let's proceed to step 7:
186 divided by 517 is 0 with a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 15930.0
Subtracting 0 from 186 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 8:
517 goes into 1860 3 times with a remainder of 309.
The number 3 becomes the next digit in our result. 
Result so far: 15930.3
If we subtract 1551 from 1860, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 9:
If we divide 3090 by 517, we get 5 and a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 15930.35
If we take 2585 away from 3090, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Advancing to step 10:
517 goes into 5050 9 times with a remainder of 397.
The next digit of our result is 9. 
Result so far: 15930.359
If we subtract 4653 from 5050, we get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 11:
When dividing 3970 by 517, we get 7 with a remainder of 351.
Record the quotient 7 as the next digit in the result. 
Result so far: 15930.3597
If we subtract 3619 from 3970, we get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 12:
517 can be fit into 3510 6 times, resulting in a remainder of 408.
Record the quotient 6 as the next digit in the result. 
Result so far: 15930.35976
If we subtract 3102 from 3510, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 13:
517 can be fit into 4080 7 times, resulting in a remainder of 461.
Write down 7 as next digit of the result. 
Result so far: 15930.359767
Subtract 3619 from 4080 to get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Let's proceed to step 14:
517 goes into 4610 8 times with a remainder of 474.
Use 8 as the next digit of our solution. 
Result so far: 15930.3597678
Subtracting 4136 from 4610 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 15:
517 can be fit into 4740 9 times, resulting in a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 15930.35976789
Deduct 4653 from 4740 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The quotient of the division is 15930.35976789, and the remainder is 8.7e-08.
