439807 ÷ 31 
The aim is to understand the frequency of 31 in 439807.

Moving on to step 1:
31 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 31

Let's proceed to step 2:
43 divided by 31 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 31 away from 43, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 31

Advancing to step 3:
129 divided by 31 is 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 5 after subtracting 124 from 129.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 31

Going ahead to step 4:
31 can be fit into 58 1 times, resulting in a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 141.0
If we take 31 away from 58, we end up with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 31

Advancing to step 5:
31 can be fit into 270 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 1418.0
The remainder is 22 after subtracting 248 from 270.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 31

On to step 6:
31 goes into 227 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 14187.0
Subtract 217 from 227 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
31 goes into 100 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 14187.3
Subtracting 93 from 100 leaves us 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.

Moving on to step 8:
31 can be fit into 70 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 14187.32
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.

Step 9:
The number 31 fits into 80 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 14187.322
If we take 62 away from 80, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 14187.322 with a balance of 0.0018.
