We look at the division of 858446 by 6 
The aim is to understand the frequency of 6 in 858446.

Going ahead to step 1:
6 goes into 8 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 6 from 8 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 6

Moving on to step 2:
The number 6 fits into 25 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 24 from 25 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 6

Moving on to step 3:
When dividing 18 by 6, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
The remainder is 0 after subtracting 18 from 18.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 6

Moving on to step 4:
The number 6 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 1430.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 6

On to step 5:
6 can be fit into 44 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 14307.0
Subtract 42 from 44 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 6

Moving on to step 6:
If we divide 26 by 6, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 143074.0
If we take 24 away from 26, 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.

Let's proceed to step 7:
The number 6 fits into 20 3 times, leaving a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 143074.3
Subtracting 18 from 20 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.

On to step 8:
20 divided by 6 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 143074.33
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.

The final result is 143074.33 with a remainder of 0.002.
