We look at the division of 44358201 by 31 
The aim is to understand the frequency of 31 in 44358201.

Step 1:
31 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 31

Let's proceed to step 2:
If we divide 44 by 31, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 31 from 44 to get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 31

Step 3:
133 divided by 31 is 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 124 from 133 leaves us with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 31

Advancing to step 4:
If we divide 95 by 31, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Subtracting 93 from 95 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 31

On to step 5:
28 divided by 31 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 1430.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 31

On to step 6:
When dividing 282 by 31, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 14309.0
Deduct 279 from 282 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 31

Step 7:
If we divide 30 by 31, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 143090.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 31

Let's proceed to step 8:
When dividing 301 by 31, we get 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 1430909.0
Subtracting 279 from 301 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
220 divided by 31 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1430909.7
If we subtract 217 from 220, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
31 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1430909.7
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
300 divided by 31 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 1430909.709
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
31 goes into 210 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1430909.7096
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.

Step 13:
31 goes into 240 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 1430909.70967
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.

On to step 14:
31 can be fit into 230 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 1430909.709677
The remainder is 13 after subtracting 217 from 230.
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 result is 1430909.709677 with a remainder of 1.3e-06.
