We look at the division of 94241221 by 519 
The aim is to understand the frequency of 519 in 94241221.

Going ahead to step 1:
9 divided by 519 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 519

On to step 2:
519 can be fit into 94 0 times, resulting in a remainder of 94.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 94 to get 94.
Fetch the next digit (2) from the dividend, attach it to 94 and continue: 942 / 519

Step 3:
519 can be fit into 942 1 times, resulting in a remainder of 423.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 519 from 942 and we're left with 423.
Append the next digit (4) from the dividend to 423 and continue with: 4234 / 519

Let's proceed to step 4:
The number 519 fits into 4234 8 times, leaving a remainder of 82.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 4152 from 4234 and we're left with 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 519

Moving on to step 5:
519 goes into 821 1 times with a remainder of 302.
Write down 1 as next digit of the result. 
Result so far: 181.0
Subtracting 519 from 821 leaves us with 302.
Grab the next digit (2) from the dividend, add it to 302, then carry on: 3022 / 519

Let's proceed to step 6:
519 goes into 3022 5 times with a remainder of 427.
Put 5 as the next digit of the answer. 
Result so far: 1815.0
If we take 2595 away from 3022, we end up with 427.
Fetch the next digit (2) from the dividend, attach it to 427 and continue: 4272 / 519

Step 7:
4272 divided by 519 is 8 with a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 18158.0
The remainder is 120 after subtracting 4152 from 4272.
Bring next digit (1) of the dividend behind the 120 and repeat the process: 1201 / 519

Let's proceed to step 8:
1201 divided by 519 is 2 with a remainder of 163.
The next digit of our result is 2. 
Result so far: 181582.0
If we subtract 1038 from 1201, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 9:
1630 divided by 519 is 3 with a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 181582.3
Deduct 1557 from 1630 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 10:
If we divide 730 by 519, we get 1 and a remainder of 211.
The next digit of our result is 1. 
Result so far: 181582.31
The remainder is 211 after subtracting 519 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Moving on to step 11:
2110 divided by 519 is 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 181582.314
The remainder is 34 after subtracting 2076 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
If we divide 340 by 519, we get 0 and a remainder of 340.
The next digit of our result is 0. 
Result so far: 181582.314
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 13:
When dividing 3400 by 519, we get 6 with a remainder of 286.
Put 6 as the next digit of the answer. 
Result so far: 181582.31406
If we subtract 3114 from 3400, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 14:
2860 divided by 519 is 5 with a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 181582.314065
Deduct 2595 from 2860 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 15:
2650 divided by 519 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 181582.3140655
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.

After the division, we end up with 181582.3140655 and a remainder of 5.5e-07.
