We're dividing 78783619 by 519 
The aim is to understand the frequency of 519 in 78783619.

Step 1:
7 divided by 519 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 519

Going ahead to step 2:
519 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 519

Step 3:
519 can be fit into 787 1 times, resulting in a remainder of 268.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 519 from 787 to get 268.
Include the next digit (8) from the dividend after 268, then repeat: 2688 / 519

On to step 4:
If we divide 2688 by 519, we get 5 and a remainder of 93.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 93 after subtracting 2595 from 2688.
Take the next digit (3) from the dividend and append it to 93, then repeat: 933 / 519

Going ahead to step 5:
933 divided by 519 is 1 with a remainder of 414.
Use 1 as the next digit of our solution. 
Result so far: 151.0
If we subtract 519 from 933, we get 414.
Append the next digit (6) from the dividend to 414 and continue with: 4146 / 519

On to step 6:
519 goes into 4146 7 times with a remainder of 513.
Put 7 as the next digit of the answer. 
Result so far: 1517.0
The remainder is 513 after subtracting 3633 from 4146.
Bring next digit (1) of the dividend behind the 513 and repeat the process: 5131 / 519

Moving on to step 7:
If we divide 5131 by 519, we get 9 and a remainder of 460.
The number 9 becomes the next digit in our result. 
Result so far: 15179.0
If we take 4671 away from 5131, we end up with 460.
Fetch the next digit (9) from the dividend, attach it to 460 and continue: 4609 / 519

Moving on to step 8:
519 goes into 4609 8 times with a remainder of 457.
Use 8 as the next digit of our solution. 
Result so far: 151798.0
Subtracting 4152 from 4609 leaves us with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 9:
When dividing 4570 by 519, we get 8 with a remainder of 418.
Use 8 as the next digit of our solution. 
Result so far: 151798.8
The remainder is 418 after subtracting 4152 from 4570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 10:
The number 519 fits into 4180 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 151798.88
If we subtract 4152 from 4180, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 151798.88 with a balance of 0.028.
