We look at the division of 843188 by 6 
The aim is to understand the frequency of 6 in 843188.

Advancing to step 1:
If we divide 8 by 6, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 6 from 8, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 6

Advancing to step 2:
If we divide 24 by 6, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 0 after subtracting 24 from 24.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 6

Moving on to step 3:
6 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 140.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 6

Step 4:
If we divide 31 by 6, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 1405.0
Subtract 30 from 31 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 6

On to step 5:
18 divided by 6 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 14053.0
If we subtract 18 from 18, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 6

Let's proceed to step 6:
The number 6 fits into 8 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 140531.0
Deduct 6 from 8 and we're left 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 7:
If we divide 20 by 6, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 140531.3
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:
20 divided by 6 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 140531.33
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.

Our division results in 140531.33 with a remaining 0.002.
