Let's divide 74043690 by 519
The aim is to understand the frequency of 519 in 74043690.

Going ahead to step 1:
The number 519 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 519

Advancing to step 2:
74 divided by 519 is 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 519

Advancing to step 3:
When dividing 740 by 519, we get 1 with a remainder of 221.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 221 after subtracting 519 from 740.
Bring next digit (4) of the dividend behind the 221 and repeat the process: 2214 / 519

Going ahead to step 4:
If we divide 2214 by 519, we get 4 and a remainder of 138.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 2076 from 2214 to get 138.
Take the next digit (3) from the dividend and append it to 138, then repeat: 1383 / 519

Advancing to step 5:
If we divide 1383 by 519, we get 2 and a remainder of 345.
The next digit of our result is 2. 
Result so far: 142.0
If we subtract 1038 from 1383, we get 345.
Take the next digit (6) from the dividend and append it to 345, then repeat: 3456 / 519

Moving on to step 6:
The number 519 fits into 3456 6 times, leaving a remainder of 342.
Record the quotient 6 as the next digit in the result. 
Result so far: 1426.0
The remainder is 342 after subtracting 3114 from 3456.
Bring next digit (9) of the dividend behind the 342 and repeat the process: 3429 / 519

On to step 7:
If we divide 3429 by 519, we get 6 and a remainder of 315.
The next digit of our result is 6. 
Result so far: 14266.0
If we take 3114 away from 3429, we end up with 315.
Bring next digit (0) of the dividend behind the 315 and repeat the process: 3150 / 519

Let's proceed to step 8:
519 can be fit into 3150 6 times, resulting in a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 142666.0
Deduct 3114 from 3150 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
519 can be fit into 360 0 times, resulting in a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 142666.0
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
3600 divided by 519 is 6 with a remainder of 486.
The next digit of our result is 6. 
Result so far: 142666.06
Subtract 3114 from 3600 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 11:
If we divide 4860 by 519, we get 9 and a remainder of 189.
The next digit of our result is 9. 
Result so far: 142666.069
If we take 4671 away from 4860, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 12:
519 can be fit into 1890 3 times, resulting in a remainder of 333.
Record the quotient 3 as the next digit in the result. 
Result so far: 142666.0693
Subtract 1557 from 1890 to get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Moving on to step 13:
519 can be fit into 3330 6 times, resulting in a remainder of 216.
The next digit of our result is 6. 
Result so far: 142666.06936
Subtracting 3114 from 3330 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 14:
The number 519 fits into 2160 4 times, leaving a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 142666.069364
Subtracting 2076 from 2160 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 15:
519 can be fit into 840 1 times, resulting in a remainder of 321.
Write down 1 as next digit of the result. 
Result so far: 142666.0693641
If we take 519 away from 840, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 16:
If we divide 3210 by 519, we get 6 and a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 142666.06936416
If we take 3114 away from 3210, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 142666.06936416 and a remainder of 9.6e-08.
