Let's divide 439413 by 31
The aim is to understand the frequency of 31 in 439413.

Let's proceed to step 1:
The number 31 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 31

Going ahead to step 2:
The number 31 fits into 43 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 31 from 43 to get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 31

Step 3:
If we divide 129 by 31, we get 4 and a remainder of 5.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 124 from 129 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 31

Moving on to step 4:
54 divided by 31 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
If we subtract 31 from 54, we get 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 31

Step 5:
31 can be fit into 231 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 1417.0
The remainder is 14 after subtracting 217 from 231.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 31

Step 6:
The number 31 fits into 143 4 times, leaving a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 14174.0
Deduct 124 from 143 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
31 goes into 190 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 14174.6
Deduct 186 from 190 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
31 can be fit into 40 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 14174.61
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
The number 31 fits into 90 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 14174.612
If we take 62 away from 90, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 14174.6129
If we take 279 away from 280, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
31 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 14174.6129
If we subtract 0 from 10, we 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.

Moving on to step 12:
31 goes into 100 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 14174.612903
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.

Going ahead to step 13:
The number 31 fits into 70 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 14174.6129032
If we subtract 62 from 70, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
80 divided by 31 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 14174.61290322
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.

Our division results in 14174.61290322 with a remaining 1.8e-08.
