Let's divide 911424 by 31
The aim is to understand the frequency of 31 in 911424.

Moving on to step 1:
31 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 31

Advancing to step 2:
The number 31 fits into 91 2 times, leaving a remainder of 29.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 29 after subtracting 62 from 91.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 31

Moving on to step 3:
If we divide 291 by 31, we get 9 and a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 29.0
The remainder is 12 after subtracting 279 from 291.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 31

Going ahead to step 4:
When dividing 124 by 31, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 294.0
Subtract 124 from 124 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 31

Step 5:
2 divided by 31 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 2940.0
If we take 0 away from 2, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 31

Moving on to step 6:
31 can be fit into 24 0 times, resulting in a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 29400.0
Deduct 0 from 24 and we're left 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.

On to step 7:
240 divided by 31 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 29400.7
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.

Step 8:
When dividing 230 by 31, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 29400.77
If we subtract 217 from 230, we 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.

After the division, we end up with 29400.77 and a remainder of 0.013.
