Let's divide 13808957 by 516
The aim is to understand the frequency of 516 in 13808957.

Advancing to step 1:
The number 516 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 516

Let's proceed to step 2:
516 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 516

On to step 3:
If we divide 138 by 516, we get 0 and a remainder of 138.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 138, we get 138.
Bring next digit (0) of the dividend behind the 138 and repeat the process: 1380 / 516

Step 4:
If we divide 1380 by 516, we get 2 and a remainder of 348.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1032 from 1380, we get 348.
Include the next digit (8) from the dividend after 348, then repeat: 3488 / 516

Let's proceed to step 5:
3488 divided by 516 is 6 with a remainder of 392.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 3096 from 3488 leaves us with 392.
Bring next digit (9) of the dividend behind the 392 and repeat the process: 3929 / 516

On to step 6:
516 goes into 3929 7 times with a remainder of 317.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
If we take 3612 away from 3929, we end up with 317.
Fetch the next digit (5) from the dividend, attach it to 317 and continue: 3175 / 516

Moving on to step 7:
If we divide 3175 by 516, we get 6 and a remainder of 79.
Write down 6 as next digit of the result. 
Result so far: 2676.0
If we subtract 3096 from 3175, we get 79.
Append the next digit (7) from the dividend to 79 and continue with: 797 / 516

Moving on to step 8:
797 divided by 516 is 1 with a remainder of 281.
Record the quotient 1 as the next digit in the result. 
Result so far: 26761.0
Subtracting 516 from 797 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Step 9:
When dividing 2810 by 516, we get 5 with a remainder of 230.
The next digit of our result is 5. 
Result so far: 26761.5
Deduct 2580 from 2810 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 10:
516 can be fit into 2300 4 times, resulting in a remainder of 236.
Put 4 as the next digit of the answer. 
Result so far: 26761.54
Subtracting 2064 from 2300 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 11:
If we divide 2360 by 516, we get 4 and a remainder of 296.
Use 4 as the next digit of our solution. 
Result so far: 26761.544
The remainder is 296 after subtracting 2064 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final result is 26761.544 with a remainder of 0.0296.
