We look at the division of 445867 by 31 
The aim is to understand the frequency of 31 in 445867.

Advancing to step 1:
31 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 31

Moving on to step 2:
31 can be fit into 44 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 31 from 44 and we're left with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 31

Step 3:
If we divide 135 by 31, we get 4 and a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 124 away from 135, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 31

On to step 4:
31 can be fit into 118 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Subtract 93 from 118 to get 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 31

Let's proceed to step 5:
When dividing 256 by 31, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 1438.0
Subtract 248 from 256 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 31

Let's proceed to step 6:
87 divided by 31 is 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 14382.0
Subtracting 62 from 87 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
31 goes into 250 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 14382.8
If we subtract 248 from 250, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
31 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 14382.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 31, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 14382.806
Subtracting 186 from 200 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
The number 31 fits into 140 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 14382.8064
Subtract 124 from 140 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
160 divided by 31 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 14382.80645
Subtracting 155 from 160 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
When dividing 50 by 31, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 14382.806451
If we take 31 away from 50, we end up 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 13:
31 goes into 190 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 14382.8064516
The remainder is 4 after subtracting 186 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 14382.80645161
Subtract 31 from 40 to 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.

In conclusion, the division gives 14382.80645161 with a balance of 9e-09.
