Let's divide 30424809 by 503
The aim is to understand the frequency of 503 in 30424809.

Going ahead to step 1:
The number 503 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 503

Let's proceed to step 2:
When dividing 30 by 503, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 503

Going ahead to step 3:
When dividing 304 by 503, we get 0 with a remainder of 304.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 304 leaves us with 304.
Fetch the next digit (2) from the dividend, attach it to 304 and continue: 3042 / 503

Let's proceed to step 4:
When dividing 3042 by 503, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 3018 from 3042 leaves us with 24.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 503

On to step 5:
If we divide 244 by 503, we get 0 and a remainder of 244.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtracting 0 from 244 leaves us with 244.
Bring next digit (8) of the dividend behind the 244 and repeat the process: 2448 / 503

Moving on to step 6:
503 goes into 2448 4 times with a remainder of 436.
Write down 4 as next digit of the result. 
Result so far: 604.0
Deduct 2012 from 2448 and we're left with 436.
Append the next digit (0) from the dividend to 436 and continue with: 4360 / 503

Step 7:
503 goes into 4360 8 times with a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 6048.0
The remainder is 336 after subtracting 4024 from 4360.
Bring next digit (9) of the dividend behind the 336 and repeat the process: 3369 / 503

On to step 8:
When dividing 3369 by 503, we get 6 with a remainder of 351.
The number 6 becomes the next digit in our result. 
Result so far: 60486.0
If we take 3018 away from 3369, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 9:
The number 503 fits into 3510 6 times, leaving a remainder of 492.
Write down 6 as next digit of the result. 
Result so far: 60486.6
Subtract 3018 from 3510 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 10:
4920 divided by 503 is 9 with a remainder of 393.
Write down 9 as next digit of the result. 
Result so far: 60486.69
The remainder is 393 after subtracting 4527 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Let's proceed to step 11:
503 goes into 3930 7 times with a remainder of 409.
Write down 7 as next digit of the result. 
Result so far: 60486.697
Deduct 3521 from 3930 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 12:
503 can be fit into 4090 8 times, resulting in a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 60486.6978
Deduct 4024 from 4090 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 13:
503 goes into 660 1 times with a remainder of 157.
Record the quotient 1 as the next digit in the result. 
Result so far: 60486.69781
If we subtract 503 from 660, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 14:
If we divide 1570 by 503, we get 3 and a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 60486.697813
Subtracting 1509 from 1570 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 15:
When dividing 610 by 503, we get 1 with a remainder of 107.
The next digit of our result is 1. 
Result so far: 60486.6978131
Subtracting 503 from 610 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 16:
503 can be fit into 1070 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 60486.69781312
The remainder is 64 after subtracting 1006 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 60486.69781312 with a remainder of 6.4e-08.
