We divide 80520103 by 508
The aim is to understand the frequency of 508 in 80520103.

Moving on to step 1:
When dividing 8 by 508, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 508

Going ahead to step 2:
508 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (5) from the dividend and append it to 80, then repeat: 805 / 508

Moving on to step 3:
508 can be fit into 805 1 times, resulting in a remainder of 297.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 508 from 805 leaves us with 297.
Include the next digit (2) from the dividend after 297, then repeat: 2972 / 508

Moving on to step 4:
508 can be fit into 2972 5 times, resulting in a remainder of 432.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 432 after subtracting 2540 from 2972.
Append the next digit (0) from the dividend to 432 and continue with: 4320 / 508

Step 5:
The number 508 fits into 4320 8 times, leaving a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Subtract 4064 from 4320 to get 256.
Include the next digit (1) from the dividend after 256, then repeat: 2561 / 508

Step 6:
The number 508 fits into 2561 5 times, leaving a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 1585.0
If we subtract 2540 from 2561, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 508

Moving on to step 7:
210 divided by 508 is 0 with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 15850.0
If we subtract 0 from 210, we get 210.
Bring next digit (3) of the dividend behind the 210 and repeat the process: 2103 / 508

Step 8:
When dividing 2103 by 508, we get 4 with a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 158504.0
The remainder is 71 after subtracting 2032 from 2103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
When dividing 710 by 508, we get 1 with a remainder of 202.
Use 1 as the next digit of our solution. 
Result so far: 158504.1
Subtracting 508 from 710 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.

Advancing to step 10:
If we divide 2020 by 508, we get 3 and a remainder of 496.
Use 3 as the next digit of our solution. 
Result so far: 158504.13
If we subtract 1524 from 2020, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 11:
508 goes into 4960 9 times with a remainder of 388.
The number 9 becomes the next digit in our result. 
Result so far: 158504.139
Deduct 4572 from 4960 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 12:
When dividing 3880 by 508, we get 7 with a remainder of 324.
Record the quotient 7 as the next digit in the result. 
Result so far: 158504.1397
The remainder is 324 after subtracting 3556 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 13:
When dividing 3240 by 508, we get 6 with a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 158504.13976
Subtract 3048 from 3240 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 14:
508 can be fit into 1920 3 times, resulting in a remainder of 396.
The next digit of our result is 3. 
Result so far: 158504.139763
Deduct 1524 from 1920 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 15:
3960 divided by 508 is 7 with a remainder of 404.
The next digit of our result is 7. 
Result so far: 158504.1397637
If we subtract 3556 from 3960, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 16:
The number 508 fits into 4040 7 times, leaving a remainder of 484.
Use 7 as the next digit of our solution. 
Result so far: 158504.13976377
Deduct 3556 from 4040 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

The final result is 158504.13976377 with a remainder of 4.84e-07.
