We're dividing 9316878 by 503 
The aim is to understand the frequency of 503 in 9316878.

Let's proceed to step 1:
The number 503 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 503

Step 2:
When dividing 93 by 503, we get 0 with a remainder of 93.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 93 and we're left with 93.
Grab the next digit (1) from the dividend, add it to 93, then carry on: 931 / 503

Moving on to step 3:
The number 503 fits into 931 1 times, leaving a remainder of 428.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 503 from 931 leaves us with 428.
Include the next digit (6) from the dividend after 428, then repeat: 4286 / 503

Step 4:
503 goes into 4286 8 times with a remainder of 262.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 4024 from 4286, we get 262.
Take the next digit (8) from the dividend and append it to 262, then repeat: 2628 / 503

Moving on to step 5:
2628 divided by 503 is 5 with a remainder of 113.
Put 5 as the next digit of the answer. 
Result so far: 185.0
The remainder is 113 after subtracting 2515 from 2628.
Include the next digit (7) from the dividend after 113, then repeat: 1137 / 503

Advancing to step 6:
503 can be fit into 1137 2 times, resulting in a remainder of 131.
Use 2 as the next digit of our solution. 
Result so far: 1852.0
The remainder is 131 after subtracting 1006 from 1137.
Grab the next digit (8) from the dividend, add it to 131, then carry on: 1318 / 503

Going ahead to step 7:
503 can be fit into 1318 2 times, resulting in a remainder of 312.
Record the quotient 2 as the next digit in the result. 
Result so far: 18522.0
If we take 1006 away from 1318, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 8:
The number 503 fits into 3120 6 times, leaving a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 18522.6
If we subtract 3018 from 3120, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 9:
1020 divided by 503 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 18522.62
If we take 1006 away from 1020, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
503 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 18522.62
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
503 can be fit into 1400 2 times, resulting in a remainder of 394.
Put 2 as the next digit of the answer. 
Result so far: 18522.6202
Deduct 1006 from 1400 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 12:
503 can be fit into 3940 7 times, resulting in a remainder of 419.
Record the quotient 7 as the next digit in the result. 
Result so far: 18522.62027
The remainder is 419 after subtracting 3521 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

On to step 13:
When dividing 4190 by 503, we get 8 with a remainder of 166.
Use 8 as the next digit of our solution. 
Result so far: 18522.620278
Subtract 4024 from 4190 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 14:
When dividing 1660 by 503, we get 3 with a remainder of 151.
The number 3 becomes the next digit in our result. 
Result so far: 18522.6202783
If we take 1509 away from 1660, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 15:
503 goes into 1510 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 18522.62027833
If we subtract 1509 from 1510, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 18522.62027833, and the remainder is 1e-09.
