Let's divide 49456757 by 519
The aim is to understand the frequency of 519 in 49456757.

Advancing to step 1:
When dividing 4 by 519, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 519

Advancing to step 2:
49 divided by 519 is 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 519

Moving on to step 3:
The number 519 fits into 494 0 times, leaving a remainder of 494.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 494 after subtracting 0 from 494.
Bring next digit (5) of the dividend behind the 494 and repeat the process: 4945 / 519

Moving on to step 4:
The number 519 fits into 4945 9 times, leaving a remainder of 274.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 4671 from 4945 and we're left with 274.
Grab the next digit (6) from the dividend, add it to 274, then carry on: 2746 / 519

On to step 5:
519 goes into 2746 5 times with a remainder of 151.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Subtracting 2595 from 2746 leaves us with 151.
Append the next digit (7) from the dividend to 151 and continue with: 1517 / 519

Advancing to step 6:
1517 divided by 519 is 2 with a remainder of 479.
Use 2 as the next digit of our solution. 
Result so far: 952.0
If we take 1038 away from 1517, we end up with 479.
Bring next digit (5) of the dividend behind the 479 and repeat the process: 4795 / 519

Advancing to step 7:
The number 519 fits into 4795 9 times, leaving a remainder of 124.
The next digit of our result is 9. 
Result so far: 9529.0
If we take 4671 away from 4795, we end up with 124.
Include the next digit (7) from the dividend after 124, then repeat: 1247 / 519

Going ahead to step 8:
When dividing 1247 by 519, we get 2 with a remainder of 209.
The number 2 becomes the next digit in our result. 
Result so far: 95292.0
The remainder is 209 after subtracting 1038 from 1247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 9:
The number 519 fits into 2090 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 95292.4
If we subtract 2076 from 2090, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 519, we get 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 95292.4
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
519 can be fit into 1400 2 times, resulting in a remainder of 362.
The next digit of our result is 2. 
Result so far: 95292.402
If we subtract 1038 from 1400, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 12:
The number 519 fits into 3620 6 times, leaving a remainder of 506.
Put 6 as the next digit of the answer. 
Result so far: 95292.4026
Subtracting 3114 from 3620 leaves us with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Going ahead to step 13:
When dividing 5060 by 519, we get 9 with a remainder of 389.
The next digit of our result is 9. 
Result so far: 95292.40269
If we subtract 4671 from 5060, we get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Going ahead to step 14:
The number 519 fits into 3890 7 times, leaving a remainder of 257.
Use 7 as the next digit of our solution. 
Result so far: 95292.402697
If we take 3633 away from 3890, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 15:
519 goes into 2570 4 times with a remainder of 494.
The next digit of our result is 4. 
Result so far: 95292.4026974
The remainder is 494 after subtracting 2076 from 2570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 16:
When dividing 4940 by 519, we get 9 with a remainder of 269.
Record the quotient 9 as the next digit in the result. 
Result so far: 95292.40269749
The remainder is 269 after subtracting 4671 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

The final result is 95292.40269749 with a remainder of 2.69e-07.
