We divide 258979 by 6
The aim is to understand the frequency of 6 in 258979.

Going ahead to step 1:
When dividing 2 by 6, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 6

On to step 2:
6 can be fit into 25 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 1 after subtracting 24 from 25.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 6

Let's proceed to step 3:
The number 6 fits into 18 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 43.0
If we take 18 away from 18, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 6

Step 4:
The number 6 fits into 9 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 431.0
Subtract 6 from 9 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 6

Advancing to step 5:
37 divided by 6 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 4316.0
If we subtract 36 from 37, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 6

Step 6:
The number 6 fits into 19 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 43163.0
Subtract 18 from 19 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
6 goes into 10 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 43163.1
Subtract 6 from 10 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 8:
40 divided by 6 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 43163.16
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.

Going ahead to step 9:
6 can be fit into 40 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 43163.166
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.

Our division results in 43163.166 with a remaining 0.0004.
