We look at the division of 69283191 by 503 
The aim is to understand the frequency of 503 in 69283191.

Moving on to step 1:
If we divide 6 by 503, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 503

Moving on to step 2:
503 goes into 69 0 times with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 503

Step 3:
The number 503 fits into 692 1 times, leaving a remainder of 189.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 189 after subtracting 503 from 692.
Include the next digit (8) from the dividend after 189, then repeat: 1898 / 503

On to step 4:
If we divide 1898 by 503, we get 3 and a remainder of 389.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1509 from 1898 to get 389.
Bring next digit (3) of the dividend behind the 389 and repeat the process: 3893 / 503

Advancing to step 5:
When dividing 3893 by 503, we get 7 with a remainder of 372.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Deduct 3521 from 3893 and we're left with 372.
Bring next digit (1) of the dividend behind the 372 and repeat the process: 3721 / 503

On to step 6:
The number 503 fits into 3721 7 times, leaving a remainder of 200.
The number 7 becomes the next digit in our result. 
Result so far: 1377.0
Subtracting 3521 from 3721 leaves us with 200.
Fetch the next digit (9) from the dividend, attach it to 200 and continue: 2009 / 503

On to step 7:
When dividing 2009 by 503, we get 3 with a remainder of 500.
Record the quotient 3 as the next digit in the result. 
Result so far: 13773.0
The remainder is 500 after subtracting 1509 from 2009.
Fetch the next digit (1) from the dividend, attach it to 500 and continue: 5001 / 503

Going ahead to step 8:
5001 divided by 503 is 9 with a remainder of 474.
The next digit of our result is 9. 
Result so far: 137739.0
If we subtract 4527 from 5001, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 9:
If we divide 4740 by 503, we get 9 and a remainder of 213.
The number 9 becomes the next digit in our result. 
Result so far: 137739.9
If we take 4527 away from 4740, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 10:
503 can be fit into 2130 4 times, resulting in a remainder of 118.
Record the quotient 4 as the next digit in the result. 
Result so far: 137739.94
Deduct 2012 from 2130 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 11:
If we divide 1180 by 503, we get 2 and a remainder of 174.
Use 2 as the next digit of our solution. 
Result so far: 137739.942
The remainder is 174 after subtracting 1006 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 12:
1740 divided by 503 is 3 with a remainder of 231.
Write down 3 as next digit of the result. 
Result so far: 137739.9423
The remainder is 231 after subtracting 1509 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 13:
If we divide 2310 by 503, we get 4 and a remainder of 298.
The next digit of our result is 4. 
Result so far: 137739.94234
The remainder is 298 after subtracting 2012 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 14:
The number 503 fits into 2980 5 times, leaving a remainder of 465.
Write down 5 as next digit of the result. 
Result so far: 137739.942345
Deduct 2515 from 2980 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 15:
When dividing 4650 by 503, we get 9 with a remainder of 123.
Use 9 as the next digit of our solution. 
Result so far: 137739.9423459
Subtracting 4527 from 4650 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 16:
1230 divided by 503 is 2 with a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 137739.94234592
If we subtract 1006 from 1230, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

In conclusion, the division gives 137739.94234592 with a balance of 2.24e-07.
