921344 ÷ 31 
The aim is to understand the frequency of 31 in 921344.

On to step 1:
31 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 31

Step 2:
The number 31 fits into 92 2 times, leaving a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 62 from 92 leaves us with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 31

Let's proceed to step 3:
When dividing 301 by 31, we get 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
The remainder is 22 after subtracting 279 from 301.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 31

Step 4:
31 goes into 223 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 297.0
The remainder is 6 after subtracting 217 from 223.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 31

On to step 5:
31 can be fit into 64 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2972.0
The remainder is 2 after subtracting 62 from 64.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 31

On to step 6:
31 goes into 24 0 times with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 29720.0
If we subtract 0 from 24, 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.

Step 7:
If we divide 240 by 31, we get 7 and a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 29720.7
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.

On to step 8:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 29720.77
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 outcome is 29720.77, with a leftover of 0.013.
