Let's divide 80698291 by 515
The aim is to understand the frequency of 515 in 80698291.

Advancing to step 1:
The number 515 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 515

Going ahead to step 2:
The number 515 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 515

Step 3:
When dividing 806 by 515, we get 1 with a remainder of 291.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 515 from 806 leaves us with 291.
Append the next digit (9) from the dividend to 291 and continue with: 2919 / 515

Advancing to step 4:
The number 515 fits into 2919 5 times, leaving a remainder of 344.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 2575 from 2919, we get 344.
Take the next digit (8) from the dividend and append it to 344, then repeat: 3448 / 515

Going ahead to step 5:
If we divide 3448 by 515, we get 6 and a remainder of 358.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
Subtract 3090 from 3448 to get 358.
Take the next digit (2) from the dividend and append it to 358, then repeat: 3582 / 515

Moving on to step 6:
The number 515 fits into 3582 6 times, leaving a remainder of 492.
The number 6 becomes the next digit in our result. 
Result so far: 1566.0
The remainder is 492 after subtracting 3090 from 3582.
Include the next digit (9) from the dividend after 492, then repeat: 4929 / 515

Step 7:
515 goes into 4929 9 times with a remainder of 294.
The next digit of our result is 9. 
Result so far: 15669.0
If we subtract 4635 from 4929, we get 294.
Append the next digit (1) from the dividend to 294 and continue with: 2941 / 515

Let's proceed to step 8:
515 goes into 2941 5 times with a remainder of 366.
The number 5 becomes the next digit in our result. 
Result so far: 156695.0
The remainder is 366 after subtracting 2575 from 2941.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 9:
When dividing 3660 by 515, we get 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 156695.7
Subtracting 3605 from 3660 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
When dividing 550 by 515, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 156695.71
Subtract 515 from 550 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
350 divided by 515 is 0 with a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 156695.71
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
3500 divided by 515 is 6 with a remainder of 410.
Write down 6 as next digit of the result. 
Result so far: 156695.7106
Deduct 3090 from 3500 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 13:
515 goes into 4100 7 times with a remainder of 495.
Use 7 as the next digit of our solution. 
Result so far: 156695.71067
If we subtract 3605 from 4100, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 14:
515 goes into 4950 9 times with a remainder of 315.
The next digit of our result is 9. 
Result so far: 156695.710679
Subtracting 4635 from 4950 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 15:
If we divide 3150 by 515, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 156695.7106796
If we subtract 3090 from 3150, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
515 can be fit into 600 1 times, resulting in a remainder of 85.
The next digit of our result is 1. 
Result so far: 156695.71067961
Subtract 515 from 600 to get 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 156695.71067961 with a balance of 8.5e-08.
