We're dividing 65321626 by 519 
The aim is to understand the frequency of 519 in 65321626.

Step 1:
519 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 519

On to step 2:
519 goes into 65 0 times with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Append the next digit (3) from the dividend to 65 and continue with: 653 / 519

Step 3:
The number 519 fits into 653 1 times, leaving a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 519 from 653 leaves us with 134.
Bring next digit (2) of the dividend behind the 134 and repeat the process: 1342 / 519

Going ahead to step 4:
519 can be fit into 1342 2 times, resulting in a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1038 from 1342, we get 304.
Fetch the next digit (1) from the dividend, attach it to 304 and continue: 3041 / 519

Advancing to step 5:
3041 divided by 519 is 5 with a remainder of 446.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we take 2595 away from 3041, we end up with 446.
Bring next digit (6) of the dividend behind the 446 and repeat the process: 4466 / 519

Going ahead to step 6:
519 can be fit into 4466 8 times, resulting in a remainder of 314.
The next digit of our result is 8. 
Result so far: 1258.0
Subtracting 4152 from 4466 leaves us with 314.
Fetch the next digit (2) from the dividend, attach it to 314 and continue: 3142 / 519

Moving on to step 7:
3142 divided by 519 is 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 12586.0
Subtracting 3114 from 3142 leaves us with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 519

On to step 8:
When dividing 286 by 519, we get 0 with a remainder of 286.
Record the quotient 0 as the next digit in the result. 
Result so far: 125860.0
Subtracting 0 from 286 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 9:
519 can be fit into 2860 5 times, resulting in a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 125860.5
The remainder is 265 after subtracting 2595 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 10:
When dividing 2650 by 519, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 125860.55
The remainder is 55 after subtracting 2595 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 125860.55, with a leftover of 0.055.
