329196 ÷ 31 
The aim is to understand the frequency of 31 in 329196.

Advancing to step 1:
The number 31 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 31

Step 2:
31 goes into 32 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 31 from 32 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 31

Step 3:
31 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 19 to get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 31

Step 4:
When dividing 191 by 31, we get 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Subtract 186 from 191 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 31

Moving on to step 5:
31 goes into 59 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1061.0
Subtract 31 from 59 to get 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 31

On to step 6:
When dividing 286 by 31, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 10619.0
Subtract 279 from 286 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 10619.2
Deduct 62 from 70 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
If we divide 80 by 31, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 10619.22
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.

The final outcome is 10619.22, with a leftover of 0.018.
