752023 ÷ 31 
The aim is to understand the frequency of 31 in 752023.

On to step 1:
The number 31 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 31

On to step 2:
31 can be fit into 75 2 times, resulting in a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 13 after subtracting 62 from 75.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 31

Moving on to step 3:
When dividing 132 by 31, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 124 from 132 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 31

Step 4:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 242.0
The remainder is 18 after subtracting 62 from 80.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 31

Step 5:
When dividing 182 by 31, we get 5 with a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 2425.0
Subtracting 155 from 182 leaves us with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 31

Going ahead to step 6:
When dividing 273 by 31, we get 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 24258.0
The remainder is 25 after subtracting 248 from 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
If we divide 250 by 31, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 24258.8
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.

On to step 8:
When dividing 20 by 31, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 24258.8
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.

Let's proceed to step 9:
31 goes into 200 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 24258.806
The remainder is 14 after subtracting 186 from 200.
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:
140 divided by 31 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 24258.8064
Deduct 124 from 140 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
If we divide 160 by 31, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 24258.80645
Deduct 155 from 160 and we're left 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.
The number 1 becomes the next digit in our result. 
Result so far: 24258.806451
Subtracting 31 from 50 leaves us 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.

Going ahead to step 13:
When dividing 190 by 31, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 24258.8064516
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.

Let's proceed to step 14:
31 goes into 40 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 24258.80645161
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.

The final result is 24258.80645161 with a remainder of 9e-09.
