We look at the division of 819386 by 6 
The aim is to understand the frequency of 6 in 819386.

Let's proceed to step 1:
6 can be fit into 8 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 6 from 8 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 6

Step 2:
6 goes into 21 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 18 from 21, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 6

Step 3:
When dividing 39 by 6, we get 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 136.0
The remainder is 3 after subtracting 36 from 39.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 6

Going ahead to step 4:
6 goes into 33 5 times with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 1365.0
The remainder is 3 after subtracting 30 from 33.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 6

Step 5:
The number 6 fits into 38 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 13656.0
If we subtract 36 from 38, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 6

On to step 6:
6 goes into 26 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 136564.0
Subtract 24 from 26 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.

Let's proceed to step 7:
When dividing 20 by 6, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 136564.3
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.

Moving on to step 8:
The number 6 fits into 20 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 136564.33
Deduct 18 from 20 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.

The quotient of the division is 136564.33, and the remainder is 0.002.
