We're dividing 638945 by 6 
The aim is to understand the frequency of 6 in 638945.

Moving on to step 1:
6 can be fit into 6 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 6 from 6 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 6

Moving on to step 2:
If we divide 3 by 6, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 6

Moving on to step 3:
38 divided by 6 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 106.0
The remainder is 2 after subtracting 36 from 38.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 6

Let's proceed to step 4:
6 can be fit into 29 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 1064.0
If we subtract 24 from 29, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 6

Going ahead to step 5:
When dividing 54 by 6, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 10649.0
If we take 54 away from 54, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 6

Moving on to step 6:
6 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 106490.0
Deduct 0 from 5 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.

Step 7:
6 goes into 50 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 106490.8
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
20 divided by 6 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 106490.83
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
The number 6 fits into 20 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 106490.833
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 106490.833 with a remainder of 0.0002.
