Let's divide 65232002 by 31
The aim is to understand the frequency of 31 in 65232002.

Advancing to step 1:
31 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 31

Advancing to step 2:
31 goes into 65 2 times with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 62 from 65 and we're left with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 31

On to step 3:
31 can be fit into 32 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 1 after subtracting 31 from 32.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 31

Moving on to step 4:
The number 31 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 210.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 31

Let's proceed to step 5:
132 divided by 31 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 2104.0
If we take 124 away from 132, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 31

Moving on to step 6:
31 goes into 80 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 21042.0
Subtracting 62 from 80 leaves us with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 31

Moving on to step 7:
180 divided by 31 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 210425.0
If we subtract 155 from 180, we get 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 31

Moving on to step 8:
When dividing 252 by 31, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 2104258.0
If we subtract 248 from 252, we get 4.
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 9:
When dividing 40 by 31, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 2104258.1
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.

Going ahead to step 10:
31 can be fit into 90 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2104258.12
Subtract 62 from 90 to get 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:
If we divide 280 by 31, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 2104258.129
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
31 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2104258.129
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.

Step 13:
31 goes into 100 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 2104258.12903
Subtract 93 from 100 to get 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:
If we divide 70 by 31, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2104258.129032
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 15:
31 goes into 80 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2104258.1290322
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.

After the division, we end up with 2104258.1290322 and a remainder of 1.8e-07.
