We look at the division of 443057 by 31 
The aim is to understand the frequency of 31 in 443057.

Advancing to step 1:
When dividing 4 by 31, we get 0 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.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 31

On to step 2:
The number 31 fits into 44 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 31 away from 44, we end up with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 31

Step 3:
31 can be fit into 133 4 times, resulting in a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 124 from 133 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 31

On to step 4:
When dividing 90 by 31, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
The remainder is 28 after subtracting 62 from 90.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 31

Let's proceed to step 5:
The number 31 fits into 285 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 1429.0
If we subtract 279 from 285, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 31

Going ahead to step 6:
If we divide 67 by 31, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 14292.0
If we take 62 away from 67, we end up 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 7:
31 can be fit into 50 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 14292.1
If we subtract 31 from 50, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
If we divide 190 by 31, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 14292.16
Subtracting 186 from 190 leaves us 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 9:
If we divide 40 by 31, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 14292.161
The remainder is 9 after subtracting 31 from 40.
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 10:
31 can be fit into 90 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 14292.1612
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.

Advancing to step 11:
When dividing 280 by 31, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 14292.16129
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
When dividing 10 by 31, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 14292.16129
Subtract 0 from 10 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.

Let's proceed to step 13:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 14292.1612903
If we take 93 away from 100, we end up 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 14:
31 goes into 70 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 14292.16129032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 14292.16129032 with a balance of 8e-09.
