520492 ÷ 6 
The aim is to understand the frequency of 6 in 520492.

On to step 1:
When dividing 5 by 6, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 6

On to step 2:
When dividing 52 by 6, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 48 away from 52, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 6

Let's proceed to step 3:
6 can be fit into 40 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtract 36 from 40 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 6

Going ahead to step 4:
6 can be fit into 44 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 867.0
Subtract 42 from 44 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 6

On to step 5:
When dividing 29 by 6, we get 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 8674.0
Subtract 24 from 29 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 6

Moving on to step 6:
When dividing 52 by 6, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 86748.0
Subtracting 48 from 52 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.

Advancing to step 7:
6 goes into 40 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 86748.6
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.

Let's proceed to step 8:
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: 86748.66
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.

After the division, we end up with 86748.66 and a remainder of 0.004.
