We divide 939073 by 31
The aim is to understand the frequency of 31 in 939073.

On to step 1:
When dividing 9 by 31, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 31

Step 2:
When dividing 93 by 31, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 93 from 93, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 31

Going ahead to step 3:
31 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 31

Step 4:
90 divided by 31 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 302.0
Deduct 62 from 90 and we're left with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 31

Advancing to step 5:
The number 31 fits into 287 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 3029.0
Deduct 279 from 287 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 31

Moving on to step 6:
The number 31 fits into 83 2 times, leaving a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 30292.0
Subtract 62 from 83 to get 21.
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 7:
The number 31 fits into 210 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 30292.6
Subtract 186 from 210 to 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.

Going ahead to step 8:
If we divide 240 by 31, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 30292.67
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.

Let's proceed to step 9:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 30292.677
Deduct 217 from 230 and we're left 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 30292.677, with a leftover of 0.0013.
