We look at the division of 8747875 by 519 
The aim is to understand the frequency of 519 in 8747875.

Going ahead to step 1:
When dividing 8 by 519, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 519

Going ahead to step 2:
519 can be fit into 87 0 times, resulting in a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Include the next digit (4) from the dividend after 87, then repeat: 874 / 519

Going ahead to step 3:
874 divided by 519 is 1 with a remainder of 355.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 519 from 874 to get 355.
Take the next digit (7) from the dividend and append it to 355, then repeat: 3557 / 519

Let's proceed to step 4:
519 can be fit into 3557 6 times, resulting in a remainder of 443.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 3114 from 3557 to get 443.
Include the next digit (8) from the dividend after 443, then repeat: 4438 / 519

Let's proceed to step 5:
519 goes into 4438 8 times with a remainder of 286.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
The remainder is 286 after subtracting 4152 from 4438.
Bring next digit (7) of the dividend behind the 286 and repeat the process: 2867 / 519

On to step 6:
519 can be fit into 2867 5 times, resulting in a remainder of 272.
Use 5 as the next digit of our solution. 
Result so far: 1685.0
Subtract 2595 from 2867 to get 272.
Include the next digit (5) from the dividend after 272, then repeat: 2725 / 519

Step 7:
When dividing 2725 by 519, we get 5 with a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 16855.0
Deduct 2595 from 2725 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 8:
If we divide 1300 by 519, we get 2 and a remainder of 262.
The number 2 becomes the next digit in our result. 
Result so far: 16855.2
Subtracting 1038 from 1300 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 9:
519 can be fit into 2620 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 16855.25
Subtract 2595 from 2620 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
519 goes into 250 0 times with a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 16855.25
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 11:
The number 519 fits into 2500 4 times, leaving a remainder of 424.
Record the quotient 4 as the next digit in the result. 
Result so far: 16855.2504
If we subtract 2076 from 2500, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 12:
The number 519 fits into 4240 8 times, leaving a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 16855.25048
The remainder is 88 after subtracting 4152 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 13:
519 can be fit into 880 1 times, resulting in a remainder of 361.
The number 1 becomes the next digit in our result. 
Result so far: 16855.250481
Subtract 519 from 880 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Let's proceed to step 14:
519 goes into 3610 6 times with a remainder of 496.
The number 6 becomes the next digit in our result. 
Result so far: 16855.2504816
The remainder is 496 after subtracting 3114 from 3610.
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 15:
4960 divided by 519 is 9 with a remainder of 289.
Put 9 as the next digit of the answer. 
Result so far: 16855.25048169
Subtract 4671 from 4960 to 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.

After the division, we end up with 16855.25048169 and a remainder of 2.89e-07.
