839970 ÷ 6 
The aim is to understand the frequency of 6 in 839970.

Step 1:
When dividing 8 by 6, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 6 from 8, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 6

Let's proceed to step 2:
6 goes into 23 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 18 away from 23, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 6

Step 3:
When dividing 59 by 6, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtracting 54 from 59 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 6

Moving on to step 4:
If we divide 59 by 6, we get 9 and a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 1399.0
The remainder is 5 after subtracting 54 from 59.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 6

Let's proceed to step 5:
When dividing 57 by 6, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 13999.0
Subtract 54 from 57 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 6

Let's proceed to step 6:
6 goes into 30 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 139995.0
The remainder is 0 after subtracting 30 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 6 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 139995.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
6 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 139995.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 139995.0 and a remainder of 0.0.
