We're dividing 639542 by 6 
The aim is to understand the frequency of 6 in 639542.

Let's proceed to step 1:
When dividing 6 by 6, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
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

Advancing to step 2:
When dividing 3 by 6, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 6

On to step 3:
39 divided by 6 is 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Deduct 36 from 39 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 6

Going ahead to step 4:
When dividing 35 by 6, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1065.0
Subtracting 30 from 35 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 6

Let's proceed to step 5:
When dividing 54 by 6, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 10659.0
Subtracting 54 from 54 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 6

Let's proceed to step 6:
6 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 106590.0
Subtracting 0 from 2 leaves us 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.

Advancing to step 7:
6 goes into 20 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 106590.3
Subtract 18 from 20 to 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.

Going ahead to step 8:
When dividing 20 by 6, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 106590.33
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 106590.33 with a remaining 0.002.
