Let's divide 68321 by 31
The aim is to understand the frequency of 31 in 68321.

Advancing to step 1:
31 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 31

On to step 2:
31 can be fit into 68 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 6 after subtracting 62 from 68.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 31

Let's proceed to step 3:
If we divide 63 by 31, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 62 from 63 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 31

Advancing to step 4:
If we divide 12 by 31, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 220.0
If we take 0 away from 12, we end up with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 31

Advancing to step 5:
The number 31 fits into 121 3 times, leaving a remainder of 28.
The next digit of our result is 3. 
Result so far: 2203.0
Subtract 93 from 121 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 6:
If we divide 280 by 31, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 2203.9
If we take 279 away from 280, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 31, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2203.9
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 2203.903
Deduct 93 from 100 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
When dividing 70 by 31, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2203.9032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
80 divided by 31 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2203.90322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 2203.90322 and a remainder of 1.8e-05.
