We're dividing 254419 by 6 
The aim is to understand the frequency of 6 in 254419.

On to step 1:
6 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 6

On to step 2:
The number 6 fits into 25 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 24 away from 25, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 6

Moving on to step 3:
6 goes into 14 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtracting 12 from 14 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 6

Step 4:
6 goes into 24 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 424.0
Deduct 24 from 24 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 6

Let's proceed to step 5:
When dividing 1 by 6, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 4240.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 6

Moving on to step 6:
When dividing 19 by 6, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 42403.0
Deduct 18 from 19 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 6, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 42403.1
If we subtract 6 from 10, 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.

Moving on to step 8:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 42403.16
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.

Moving on to step 9:
When dividing 40 by 6, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 42403.166
If we take 36 away from 40, we end up 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 42403.166 with a remaining 0.0004.
