We look at the division of 223575 by 6 
The aim is to understand the frequency of 6 in 223575.

Advancing to step 1:
6 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 6

Going ahead to step 2:
22 divided by 6 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 18 from 22, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 6

Step 3:
If we divide 43 by 6, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 37.0
The remainder is 1 after subtracting 42 from 43.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 6

Let's proceed to step 4:
The number 6 fits into 15 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 372.0
The remainder is 3 after subtracting 12 from 15.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 6

On to step 5:
37 divided by 6 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 3726.0
If we take 36 away from 37, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 6

Going ahead to step 6:
6 goes into 15 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 37262.0
The remainder is 3 after subtracting 12 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
6 goes into 30 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 37262.5
If we subtract 30 from 30, we 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.

Going ahead to step 8:
6 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 37262.5
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.

Moving on to step 9:
6 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37262.5
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.

The quotient of the division is 37262.5, and the remainder is 0.0.
