We look at the division of 28420 by 6 
The aim is to understand the frequency of 6 in 28420.

Advancing to step 1:
6 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 6

Advancing to step 2:
28 divided by 6 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 4 after subtracting 24 from 28.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 6

Moving on to step 3:
When dividing 44 by 6, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Deduct 42 from 44 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 6

Step 4:
When dividing 22 by 6, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 473.0
The remainder is 4 after subtracting 18 from 22.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 6

Advancing to step 5:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 4736.0
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.

Moving on to step 6:
When dividing 40 by 6, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 4736.6
Subtract 36 from 40 to 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.

On to step 7:
The number 6 fits into 40 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 4736.66
Subtracting 36 from 40 leaves us 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.

In conclusion, the division gives 4736.66 with a balance of 0.004.
