80614172 divided by 515 
The aim is to understand the frequency of 515 in 80614172.

Step 1:
If we divide 8 by 515, we get 0 and 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.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 515

Let's proceed to step 2:
515 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 515

Going ahead to step 3:
If we divide 806 by 515, we get 1 and a remainder of 291.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 291 after subtracting 515 from 806.
Take the next digit (1) from the dividend and append it to 291, then repeat: 2911 / 515

Going ahead to step 4:
515 can be fit into 2911 5 times, resulting in a remainder of 336.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2575 away from 2911, we end up with 336.
Bring next digit (4) of the dividend behind the 336 and repeat the process: 3364 / 515

Let's proceed to step 5:
515 goes into 3364 6 times with a remainder of 274.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Subtract 3090 from 3364 to get 274.
Include the next digit (1) from the dividend after 274, then repeat: 2741 / 515

Moving on to step 6:
When dividing 2741 by 515, we get 5 with a remainder of 166.
Write down 5 as next digit of the result. 
Result so far: 1565.0
Deduct 2575 from 2741 and we're left with 166.
Append the next digit (7) from the dividend to 166 and continue with: 1667 / 515

On to step 7:
If we divide 1667 by 515, we get 3 and a remainder of 122.
Use 3 as the next digit of our solution. 
Result so far: 15653.0
Subtracting 1545 from 1667 leaves us with 122.
Include the next digit (2) from the dividend after 122, then repeat: 1222 / 515

Advancing to step 8:
515 goes into 1222 2 times with a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 156532.0
Deduct 1030 from 1222 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 9:
515 goes into 1920 3 times with a remainder of 375.
Record the quotient 3 as the next digit in the result. 
Result so far: 156532.3
Subtracting 1545 from 1920 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 10:
515 can be fit into 3750 7 times, resulting in a remainder of 145.
The next digit of our result is 7. 
Result so far: 156532.37
The remainder is 145 after subtracting 3605 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 11:
The number 515 fits into 1450 2 times, leaving a remainder of 420.
The next digit of our result is 2. 
Result so far: 156532.372
Deduct 1030 from 1450 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 12:
When dividing 4200 by 515, we get 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 156532.3728
Subtracting 4120 from 4200 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
If we divide 800 by 515, we get 1 and a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 156532.37281
The remainder is 285 after subtracting 515 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 14:
2850 divided by 515 is 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 156532.372815
Subtracting 2575 from 2850 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 15:
The number 515 fits into 2750 5 times, leaving a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 156532.3728155
If we subtract 2575 from 2750, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final outcome is 156532.3728155, with a leftover of 1.75e-06.
