We're dividing 636752 by 31 
The aim is to understand the frequency of 31 in 636752.

Moving on to step 1:
6 divided by 31 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 31

On to step 2:
When dividing 63 by 31, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 62 from 63 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 31

Advancing to step 3:
If we divide 16 by 31, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 31

Let's proceed to step 4:
The number 31 fits into 167 5 times, leaving a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 205.0
Deduct 155 from 167 and we're left with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 31

Let's proceed to step 5:
31 can be fit into 125 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 2054.0
If we subtract 124 from 125, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 31

Moving on to step 6:
If we divide 12 by 31, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 20540.0
The remainder is 12 after subtracting 0 from 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
120 divided by 31 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 20540.3
Deduct 93 from 120 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
The number 31 fits into 270 8 times, leaving a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 20540.38
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
If we divide 220 by 31, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 20540.387
If we take 217 away from 220, we end up with 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:
If we divide 30 by 31, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 20540.387
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
300 divided by 31 is 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 20540.38709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
If we divide 210 by 31, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 20540.387096
Subtracting 186 from 210 leaves us with 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:
If we divide 240 by 31, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 20540.3870967
If we take 217 away from 240, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 14:
When dividing 230 by 31, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 20540.38709677
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.

After the division, we end up with 20540.38709677 and a remainder of 1.3e-08.
