We're dividing 77832039 by 503 
The aim is to understand the frequency of 503 in 77832039.

Moving on to step 1:
7 divided by 503 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 503

Let's proceed to step 2:
503 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 503

Going ahead to step 3:
778 divided by 503 is 1 with a remainder of 275.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 503 from 778 and we're left with 275.
Bring next digit (3) of the dividend behind the 275 and repeat the process: 2753 / 503

Let's proceed to step 4:
When dividing 2753 by 503, we get 5 with a remainder of 238.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 2515 from 2753 to get 238.
Fetch the next digit (2) from the dividend, attach it to 238 and continue: 2382 / 503

Going ahead to step 5:
503 goes into 2382 4 times with a remainder of 370.
Write down 4 as next digit of the result. 
Result so far: 154.0
Deduct 2012 from 2382 and we're left with 370.
Bring next digit (0) of the dividend behind the 370 and repeat the process: 3700 / 503

Step 6:
If we divide 3700 by 503, we get 7 and a remainder of 179.
Use 7 as the next digit of our solution. 
Result so far: 1547.0
If we subtract 3521 from 3700, we get 179.
Append the next digit (3) from the dividend to 179 and continue with: 1793 / 503

Step 7:
If we divide 1793 by 503, we get 3 and a remainder of 284.
Put 3 as the next digit of the answer. 
Result so far: 15473.0
If we subtract 1509 from 1793, we get 284.
Include the next digit (9) from the dividend after 284, then repeat: 2849 / 503

Step 8:
2849 divided by 503 is 5 with a remainder of 334.
Write down 5 as next digit of the result. 
Result so far: 154735.0
Subtracting 2515 from 2849 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 9:
3340 divided by 503 is 6 with a remainder of 322.
The next digit of our result is 6. 
Result so far: 154735.6
Subtracting 3018 from 3340 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 10:
If we divide 3220 by 503, we get 6 and a remainder of 202.
Use 6 as the next digit of our solution. 
Result so far: 154735.66
Subtracting 3018 from 3220 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The final result is 154735.66 with a remainder of 0.202.
