Let's divide 63484083 by 503
The aim is to understand the frequency of 503 in 63484083.

Step 1:
6 divided by 503 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 503

Moving on to step 2:
63 divided by 503 is 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 503

Let's proceed to step 3:
503 can be fit into 634 1 times, resulting in a remainder of 131.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 503 away from 634, we end up with 131.
Fetch the next digit (8) from the dividend, attach it to 131 and continue: 1318 / 503

Let's proceed to step 4:
1318 divided by 503 is 2 with a remainder of 312.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 312 after subtracting 1006 from 1318.
Take the next digit (4) from the dividend and append it to 312, then repeat: 3124 / 503

Let's proceed to step 5:
If we divide 3124 by 503, we get 6 and a remainder of 106.
The next digit of our result is 6. 
Result so far: 126.0
Subtracting 3018 from 3124 leaves us with 106.
Append the next digit (0) from the dividend to 106 and continue with: 1060 / 503

On to step 6:
503 goes into 1060 2 times with a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 1262.0
Deduct 1006 from 1060 and we're left with 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 503

On to step 7:
The number 503 fits into 548 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 12621.0
The remainder is 45 after subtracting 503 from 548.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 503

On to step 8:
453 divided by 503 is 0 with a remainder of 453.
Use 0 as the next digit of our solution. 
Result so far: 126210.0
Subtracting 0 from 453 leaves us with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Step 9:
When dividing 4530 by 503, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 126210.9
The remainder is 3 after subtracting 4527 from 4530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
When dividing 30 by 503, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 126210.9
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
If we divide 300 by 503, we get 0 and a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 126210.9
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 126210.9 and a remainder of 0.03.
