We divide 19599798 by 503
The aim is to understand the frequency of 503 in 19599798.

Moving on to step 1:
The number 503 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 503

On to step 2:
If we divide 19 by 503, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 503

Going ahead to step 3:
The number 503 fits into 195 0 times, leaving a remainder of 195.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 195 to get 195.
Append the next digit (9) from the dividend to 195 and continue with: 1959 / 503

Going ahead to step 4:
The number 503 fits into 1959 3 times, leaving a remainder of 450.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 450 after subtracting 1509 from 1959.
Append the next digit (9) from the dividend to 450 and continue with: 4509 / 503

Going ahead to step 5:
503 goes into 4509 8 times with a remainder of 485.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we take 4024 away from 4509, we end up with 485.
Bring next digit (7) of the dividend behind the 485 and repeat the process: 4857 / 503

Advancing to step 6:
If we divide 4857 by 503, we get 9 and a remainder of 330.
Record the quotient 9 as the next digit in the result. 
Result so far: 389.0
Deduct 4527 from 4857 and we're left with 330.
Append the next digit (9) from the dividend to 330 and continue with: 3309 / 503

Moving on to step 7:
The number 503 fits into 3309 6 times, leaving a remainder of 291.
Use 6 as the next digit of our solution. 
Result so far: 3896.0
Subtracting 3018 from 3309 leaves us with 291.
Take the next digit (8) from the dividend and append it to 291, then repeat: 2918 / 503

Advancing to step 8:
When dividing 2918 by 503, we get 5 with a remainder of 403.
Write down 5 as next digit of the result. 
Result so far: 38965.0
The remainder is 403 after subtracting 2515 from 2918.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Going ahead to step 9:
4030 divided by 503 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 38965.8
Subtract 4024 from 4030 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
503 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 38965.8
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
When dividing 600 by 503, we get 1 with a remainder of 97.
Record the quotient 1 as the next digit in the result. 
Result so far: 38965.801
Subtracting 503 from 600 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 12:
If we divide 970 by 503, we get 1 and a remainder of 467.
Write down 1 as next digit of the result. 
Result so far: 38965.8011
Deduct 503 from 970 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

The final outcome is 38965.8011, with a leftover of 0.00467.
