We're dividing 90560928 by 519 
The aim is to understand the frequency of 519 in 90560928.

On to step 1:
519 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 519

On to step 2:
519 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 519

Step 3:
The number 519 fits into 905 1 times, leaving a remainder of 386.
The next digit of our result is 1. 
Result so far: 1.0
If we take 519 away from 905, we end up with 386.
Grab the next digit (6) from the dividend, add it to 386, then carry on: 3866 / 519

Step 4:
The number 519 fits into 3866 7 times, leaving a remainder of 233.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 3633 away from 3866, we end up with 233.
Append the next digit (0) from the dividend to 233 and continue with: 2330 / 519

Moving on to step 5:
If we divide 2330 by 519, we get 4 and a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
If we take 2076 away from 2330, we end up with 254.
Bring next digit (9) of the dividend behind the 254 and repeat the process: 2549 / 519

Advancing to step 6:
When dividing 2549 by 519, we get 4 with a remainder of 473.
Use 4 as the next digit of our solution. 
Result so far: 1744.0
If we take 2076 away from 2549, we end up with 473.
Bring next digit (2) of the dividend behind the 473 and repeat the process: 4732 / 519

Moving on to step 7:
519 can be fit into 4732 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 17449.0
Subtracting 4671 from 4732 leaves us with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 519

On to step 8:
The number 519 fits into 618 1 times, leaving a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 174491.0
The remainder is 99 after subtracting 519 from 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 9:
If we divide 990 by 519, we get 1 and a remainder of 471.
The next digit of our result is 1. 
Result so far: 174491.1
Deduct 519 from 990 and we're left with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Moving on to step 10:
If we divide 4710 by 519, we get 9 and a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 174491.19
Subtract 4671 from 4710 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 11:
When dividing 390 by 519, we get 0 with a remainder of 390.
The next digit of our result is 0. 
Result so far: 174491.19
Deduct 0 from 390 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 12:
519 goes into 3900 7 times with a remainder of 267.
The number 7 becomes the next digit in our result. 
Result so far: 174491.1907
Subtract 3633 from 3900 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Going ahead to step 13:
When dividing 2670 by 519, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 174491.19075
Subtract 2595 from 2670 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 14:
The number 519 fits into 750 1 times, leaving a remainder of 231.
The number 1 becomes the next digit in our result. 
Result so far: 174491.190751
Subtract 519 from 750 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 15:
The number 519 fits into 2310 4 times, leaving a remainder of 234.
Record the quotient 4 as the next digit in the result. 
Result so far: 174491.1907514
If we take 2076 away from 2310, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 16:
The number 519 fits into 2340 4 times, leaving a remainder of 264.
Put 4 as the next digit of the answer. 
Result so far: 174491.19075144
The remainder is 264 after subtracting 2076 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

In conclusion, the division gives 174491.19075144 with a balance of 2.64e-07.
