202643 divided by 6 
The aim is to understand the frequency of 6 in 202643.

On to step 1:
6 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 6

On to step 2:
The number 6 fits into 20 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 18 from 20, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 6

On to step 3:
22 divided by 6 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Deduct 18 from 22 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 6

Let's proceed to step 4:
The number 6 fits into 46 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 337.0
The remainder is 4 after subtracting 42 from 46.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 6

Advancing to step 5:
The number 6 fits into 44 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 3377.0
Deduct 42 from 44 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 6

Advancing to step 6:
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: 33773.0
If we take 18 away from 23, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
When dividing 50 by 6, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 33773.8
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
6 goes into 20 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 33773.83
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
When dividing 20 by 6, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 33773.833
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 33773.833 and a remainder of 0.0002.
