We're dividing 491368 by 6 
The aim is to understand the frequency of 6 in 491368.

Let's proceed to step 1:
When dividing 4 by 6, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 6

Step 2:
The number 6 fits into 49 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 48 from 49, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 6

Moving on to step 3:
11 divided by 6 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we take 6 away from 11, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 6

Going ahead to step 4:
The number 6 fits into 53 8 times, leaving a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 818.0
If we take 48 away from 53, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 6

Step 5:
56 divided by 6 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 8189.0
If we subtract 54 from 56, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 6

Advancing to step 6:
28 divided by 6 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 81894.0
Deduct 24 from 28 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
6 goes into 40 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 81894.6
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
6 can be fit into 40 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 81894.66
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 81894.66 and a remainder of 0.004.
