We're dividing 620433 by 31 
The aim is to understand the frequency of 31 in 620433.

Moving on to step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 31

Let's proceed to step 2:
31 can be fit into 62 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 62 from 62 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 31

On to step 3:
0 divided by 31 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 31

On to step 4:
The number 31 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 200.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 31

Advancing to step 5:
The number 31 fits into 43 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 2001.0
Subtract 31 from 43 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 31

Going ahead to step 6:
When dividing 123 by 31, we get 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 20013.0
If we take 93 away from 123, 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.

Let's proceed to step 7:
When dividing 300 by 31, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 20013.9
Subtracting 279 from 300 leaves us 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.

Step 8:
31 can be fit into 210 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 20013.96
Deduct 186 from 210 and we're left 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.

Going ahead to step 9:
When dividing 240 by 31, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 20013.967
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.

Advancing to step 10:
230 divided by 31 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 20013.9677
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 20013.9677, and the remainder is 0.00013.
