We divide 42400 by 6
The aim is to understand the frequency of 6 in 42400.

Advancing to step 1:
The number 6 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 6

Advancing to step 2:
When dividing 42 by 6, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 42 from 42 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 6

Going ahead to step 3:
When dividing 4 by 6, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 6

Going ahead to step 4:
40 divided by 6 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 706.0
If we take 36 away from 40, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 6

Moving on 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: 7066.0
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.

Moving on to step 6:
40 divided by 6 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 7066.6
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.

Let's proceed to step 7:
When dividing 40 by 6, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 7066.66
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.

Our division results in 7066.66 with a remaining 0.004.
