Let's divide 83868629 by 519
The aim is to understand the frequency of 519 in 83868629.

On to step 1:
When dividing 8 by 519, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 519

Step 2:
When dividing 83 by 519, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Take the next digit (8) from the dividend and append it to 83, then repeat: 838 / 519

Advancing to step 3:
If we divide 838 by 519, we get 1 and a remainder of 319.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 519 from 838 and we're left with 319.
Grab the next digit (6) from the dividend, add it to 319, then carry on: 3196 / 519

On to step 4:
When dividing 3196 by 519, we get 6 with a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 3114 from 3196 and we're left with 82.
Append the next digit (8) from the dividend to 82 and continue with: 828 / 519

Let's proceed to step 5:
519 goes into 828 1 times with a remainder of 309.
Write down 1 as next digit of the result. 
Result so far: 161.0
Subtracting 519 from 828 leaves us with 309.
Grab the next digit (6) from the dividend, add it to 309, then carry on: 3096 / 519

Moving on to step 6:
3096 divided by 519 is 5 with a remainder of 501.
The number 5 becomes the next digit in our result. 
Result so far: 1615.0
Subtracting 2595 from 3096 leaves us with 501.
Grab the next digit (2) from the dividend, add it to 501, then carry on: 5012 / 519

Going ahead to step 7:
When dividing 5012 by 519, we get 9 with a remainder of 341.
The next digit of our result is 9. 
Result so far: 16159.0
Subtract 4671 from 5012 to get 341.
Append the next digit (9) from the dividend to 341 and continue with: 3419 / 519

Advancing to step 8:
When dividing 3419 by 519, we get 6 with a remainder of 305.
Write down 6 as next digit of the result. 
Result so far: 161596.0
If we take 3114 away from 3419, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 9:
The number 519 fits into 3050 5 times, leaving a remainder of 455.
Record the quotient 5 as the next digit in the result. 
Result so far: 161596.5
Subtracting 2595 from 3050 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Step 10:
4550 divided by 519 is 8 with a remainder of 398.
The next digit of our result is 8. 
Result so far: 161596.58
If we take 4152 away from 4550, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 11:
If we divide 3980 by 519, we get 7 and a remainder of 347.
The next digit of our result is 7. 
Result so far: 161596.587
The remainder is 347 after subtracting 3633 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Step 12:
3470 divided by 519 is 6 with a remainder of 356.
Write down 6 as next digit of the result. 
Result so far: 161596.5876
If we take 3114 away from 3470, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 13:
519 can be fit into 3560 6 times, resulting in a remainder of 446.
Put 6 as the next digit of the answer. 
Result so far: 161596.58766
Subtract 3114 from 3560 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

The final outcome is 161596.58766, with a leftover of 0.000446.
