We look at the division of 608495 by 31 
The aim is to understand the frequency of 31 in 608495.

Let's proceed to step 1:
31 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 31

Going ahead to step 2:
60 divided by 31 is 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 29 after subtracting 31 from 60.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 31

Advancing to step 3:
298 divided by 31 is 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 279 from 298 leaves us with 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 31

Going ahead to step 4:
When dividing 194 by 31, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 196.0
Subtract 186 from 194 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 31

Moving on to step 5:
When dividing 89 by 31, we get 2 with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 1962.0
The remainder is 27 after subtracting 62 from 89.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 31

Step 6:
31 goes into 275 8 times with a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 19628.0
If we subtract 248 from 275, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
31 can be fit into 270 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 19628.8
Subtracting 248 from 270 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
The number 31 fits into 220 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 19628.87
Subtract 217 from 220 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
31 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 19628.87
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
If we divide 300 by 31, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 19628.8709
The remainder is 21 after subtracting 279 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
If we divide 210 by 31, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 19628.87096
If we take 186 away from 210, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
31 goes into 240 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 19628.870967
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
When dividing 230 by 31, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 19628.8709677
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 19628.8709677 with a remainder of 1.3e-07.
