65273851 divided by 503 
The aim is to understand the frequency of 503 in 65273851.

Advancing to step 1:
If we divide 6 by 503, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 503

Let's proceed to step 2:
65 divided by 503 is 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 503

Let's proceed to step 3:
503 goes into 652 1 times with a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 503 from 652, we get 149.
Grab the next digit (7) from the dividend, add it to 149, then carry on: 1497 / 503

Step 4:
If we divide 1497 by 503, we get 2 and a remainder of 491.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1006 from 1497 leaves us with 491.
Append the next digit (3) from the dividend to 491 and continue with: 4913 / 503

Step 5:
4913 divided by 503 is 9 with a remainder of 386.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
The remainder is 386 after subtracting 4527 from 4913.
Take the next digit (8) from the dividend and append it to 386, then repeat: 3868 / 503

Step 6:
The number 503 fits into 3868 7 times, leaving a remainder of 347.
Put 7 as the next digit of the answer. 
Result so far: 1297.0
If we subtract 3521 from 3868, we get 347.
Bring next digit (5) of the dividend behind the 347 and repeat the process: 3475 / 503

Let's proceed to step 7:
When dividing 3475 by 503, we get 6 with a remainder of 457.
Use 6 as the next digit of our solution. 
Result so far: 12976.0
If we subtract 3018 from 3475, we get 457.
Grab the next digit (1) from the dividend, add it to 457, then carry on: 4571 / 503

Step 8:
4571 divided by 503 is 9 with a remainder of 44.
The next digit of our result is 9. 
Result so far: 129769.0
Subtract 4527 from 4571 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
When dividing 440 by 503, we get 0 with a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 129769.0
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 10:
4400 divided by 503 is 8 with a remainder of 376.
Record the quotient 8 as the next digit in the result. 
Result so far: 129769.08
If we take 4024 away from 4400, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 11:
If we divide 3760 by 503, we get 7 and a remainder of 239.
The number 7 becomes the next digit in our result. 
Result so far: 129769.087
If we take 3521 away from 3760, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 12:
If we divide 2390 by 503, we get 4 and a remainder of 378.
Put 4 as the next digit of the answer. 
Result so far: 129769.0874
Subtracting 2012 from 2390 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 13:
The number 503 fits into 3780 7 times, leaving a remainder of 259.
Use 7 as the next digit of our solution. 
Result so far: 129769.08747
If we subtract 3521 from 3780, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Going ahead to step 14:
503 goes into 2590 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 129769.087475
Subtracting 2515 from 2590 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 15:
750 divided by 503 is 1 with a remainder of 247.
Record the quotient 1 as the next digit in the result. 
Result so far: 129769.0874751
Subtract 503 from 750 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 16:
If we divide 2470 by 503, we get 4 and a remainder of 458.
The next digit of our result is 4. 
Result so far: 129769.08747514
The remainder is 458 after subtracting 2012 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Our division results in 129769.08747514 with a remaining 4.58e-07.
