Let's divide 17428830 by 519
The aim is to understand the frequency of 519 in 17428830.

On to step 1:
1 divided by 519 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 519

Let's proceed to step 2:
519 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 519

Going ahead to step 3:
When dividing 174 by 519, we get 0 with a remainder of 174.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 174 leaves us with 174.
Include the next digit (2) from the dividend after 174, then repeat: 1742 / 519

On to step 4:
1742 divided by 519 is 3 with a remainder of 185.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1557 from 1742, we get 185.
Include the next digit (8) from the dividend after 185, then repeat: 1858 / 519

Step 5:
519 can be fit into 1858 3 times, resulting in a remainder of 301.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we subtract 1557 from 1858, we get 301.
Include the next digit (8) from the dividend after 301, then repeat: 3018 / 519

Moving on to step 6:
The number 519 fits into 3018 5 times, leaving a remainder of 423.
Use 5 as the next digit of our solution. 
Result so far: 335.0
If we subtract 2595 from 3018, we get 423.
Grab the next digit (3) from the dividend, add it to 423, then carry on: 4233 / 519

Going ahead to step 7:
If we divide 4233 by 519, we get 8 and a remainder of 81.
The number 8 becomes the next digit in our result. 
Result so far: 3358.0
If we subtract 4152 from 4233, we get 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 519

Advancing to step 8:
810 divided by 519 is 1 with a remainder of 291.
Write down 1 as next digit of the result. 
Result so far: 33581.0
If we subtract 519 from 810, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 9:
519 goes into 2910 5 times with a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 33581.5
Deduct 2595 from 2910 and we're left 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.

Let's proceed to step 10:
519 goes into 3150 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 33581.56
Subtracting 3114 from 3150 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
519 can be fit into 360 0 times, resulting in a remainder of 360.
The next digit of our result is 0. 
Result so far: 33581.56
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 12:
The number 519 fits into 3600 6 times, leaving a remainder of 486.
The number 6 becomes the next digit in our result. 
Result so far: 33581.5606
Subtracting 3114 from 3600 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 13:
When dividing 4860 by 519, we get 9 with a remainder of 189.
Use 9 as the next digit of our solution. 
Result so far: 33581.56069
If we subtract 4671 from 4860, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 14:
If we divide 1890 by 519, we get 3 and a remainder of 333.
The number 3 becomes the next digit in our result. 
Result so far: 33581.560693
Deduct 1557 from 1890 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Let's proceed to step 15:
The number 519 fits into 3330 6 times, leaving a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 33581.5606936
Subtracting 3114 from 3330 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 16:
519 can be fit into 2160 4 times, resulting in a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 33581.56069364
Subtracting 2076 from 2160 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 33581.56069364, with a leftover of 8.4e-08.
