We're dividing 809282 by 31 
The aim is to understand the frequency of 31 in 809282.

Moving on to step 1:
The number 31 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 31

Moving on to step 2:
If we divide 80 by 31, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 18 after subtracting 62 from 80.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 31

Step 3:
31 goes into 189 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we subtract 186 from 189, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 31

Advancing to step 4:
If we divide 32 by 31, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 261.0
Subtracting 31 from 32 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 31

Let's proceed to step 5:
The number 31 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 2610.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 31

Moving on to step 6:
When dividing 182 by 31, we get 5 with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 26105.0
If we take 155 away from 182, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
When dividing 270 by 31, we get 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 26105.8
If we take 248 away from 270, we end up 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.

On to step 8:
31 goes into 220 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 26105.87
If we subtract 217 from 220, we 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.

Moving on to step 9:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 26105.87
If we take 0 away from 30, we end up 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.

Moving on to step 10:
31 goes into 300 9 times with a remainder of 21.
The next digit of our result is 9. 
Result so far: 26105.8709
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:
210 divided by 31 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 26105.87096
If we subtract 186 from 210, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
31 goes into 240 7 times with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 26105.870967
Subtract 217 from 240 to 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.

On to step 13:
If we divide 230 by 31, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 26105.8709677
If we take 217 away from 230, we end up with 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 outcome is 26105.8709677, with a leftover of 1.3e-07.
