64286850 ÷ 519 
The aim is to understand the frequency of 519 in 64286850.

Let's proceed to step 1:
519 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 519

Let's proceed to step 2:
If we divide 64 by 519, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 519

Going ahead to step 3:
642 divided by 519 is 1 with a remainder of 123.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 123 after subtracting 519 from 642.
Fetch the next digit (8) from the dividend, attach it to 123 and continue: 1238 / 519

Step 4:
If we divide 1238 by 519, we get 2 and a remainder of 200.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1038 from 1238 and we're left with 200.
Take the next digit (6) from the dividend and append it to 200, then repeat: 2006 / 519

Moving on to step 5:
If we divide 2006 by 519, we get 3 and a remainder of 449.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtracting 1557 from 2006 leaves us with 449.
Include the next digit (8) from the dividend after 449, then repeat: 4498 / 519

Going ahead to step 6:
519 goes into 4498 8 times with a remainder of 346.
The next digit of our result is 8. 
Result so far: 1238.0
If we subtract 4152 from 4498, we get 346.
Take the next digit (5) from the dividend and append it to 346, then repeat: 3465 / 519

Moving on to step 7:
519 goes into 3465 6 times with a remainder of 351.
Use 6 as the next digit of our solution. 
Result so far: 12386.0
If we subtract 3114 from 3465, we get 351.
Bring next digit (0) of the dividend behind the 351 and repeat the process: 3510 / 519

Going ahead to step 8:
The number 519 fits into 3510 6 times, leaving a remainder of 396.
Write down 6 as next digit of the result. 
Result so far: 123866.0
The remainder is 396 after subtracting 3114 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 9:
3960 divided by 519 is 7 with a remainder of 327.
The next digit of our result is 7. 
Result so far: 123866.7
If we take 3633 away from 3960, we end up with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 10:
The number 519 fits into 3270 6 times, leaving a remainder of 156.
Write down 6 as next digit of the result. 
Result so far: 123866.76
If we subtract 3114 from 3270, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
If we divide 1560 by 519, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 123866.763
If we take 1557 away from 1560, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
When dividing 30 by 519, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 123866.763
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
519 goes into 300 0 times with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 123866.763
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 123866.763 with a remainder of 0.0003.
