We're dividing 11931787 by 519 
The aim is to understand the frequency of 519 in 11931787.

Going ahead to step 1:
519 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 519

On to step 2:
519 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 519

Moving on to step 3:
519 goes into 119 0 times with a remainder of 119.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 119, we end up with 119.
Bring next digit (3) of the dividend behind the 119 and repeat the process: 1193 / 519

Advancing to step 4:
519 goes into 1193 2 times with a remainder of 155.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1038 from 1193, we get 155.
Grab the next digit (1) from the dividend, add it to 155, then carry on: 1551 / 519

Let's proceed to step 5:
If we divide 1551 by 519, we get 2 and a remainder of 513.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 1038 from 1551 to get 513.
Fetch the next digit (7) from the dividend, attach it to 513 and continue: 5137 / 519

Moving on to step 6:
If we divide 5137 by 519, we get 9 and a remainder of 466.
Put 9 as the next digit of the answer. 
Result so far: 229.0
The remainder is 466 after subtracting 4671 from 5137.
Bring next digit (8) of the dividend behind the 466 and repeat the process: 4668 / 519

Step 7:
The number 519 fits into 4668 8 times, leaving a remainder of 516.
Record the quotient 8 as the next digit in the result. 
Result so far: 2298.0
If we subtract 4152 from 4668, we get 516.
Include the next digit (7) from the dividend after 516, then repeat: 5167 / 519

On to step 8:
519 goes into 5167 9 times with a remainder of 496.
The number 9 becomes the next digit in our result. 
Result so far: 22989.0
Subtract 4671 from 5167 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 9:
When dividing 4960 by 519, we get 9 with a remainder of 289.
Put 9 as the next digit of the answer. 
Result so far: 22989.9
If we subtract 4671 from 4960, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Going ahead to step 10:
If we divide 2890 by 519, we get 5 and a remainder of 295.
The number 5 becomes the next digit in our result. 
Result so far: 22989.95
If we subtract 2595 from 2890, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 11:
519 goes into 2950 5 times with a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 22989.955
The remainder is 355 after subtracting 2595 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

The final outcome is 22989.955, with a leftover of 0.0355.
