We look at the division of 445075 by 31 
The aim is to understand the frequency of 31 in 445075.

Advancing to step 1:
31 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 31

Advancing to step 2:
If we divide 44 by 31, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 31 from 44 to get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 31

Step 3:
When dividing 135 by 31, we get 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 124 from 135 leaves us with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 31

Let's proceed to step 4:
31 goes into 110 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 143.0
Subtract 93 from 110 to get 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 31

On to step 5:
When dividing 177 by 31, we get 5 with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 1435.0
If we take 155 away from 177, we end up with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 31

Advancing to step 6:
If we divide 225 by 31, we get 7 and a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 14357.0
If we subtract 217 from 225, 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.

Moving on to step 7:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 14357.2
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
31 goes into 180 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 14357.25
If we subtract 155 from 180, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
The number 31 fits into 250 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 14357.258
The remainder is 2 after subtracting 248 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
20 divided by 31 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 14357.258
Subtracting 0 from 20 leaves us with 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 11:
If we divide 200 by 31, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 14357.25806
Subtract 186 from 200 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
If we divide 140 by 31, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 14357.258064
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 13:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 14357.2580645
Subtract 155 from 160 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
When dividing 50 by 31, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 14357.25806451
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 14357.25806451 with a balance of 1.9e-08.
