We look at the division of 253820 by 9 
The aim is to understand the frequency of 9 in 253820.

Going ahead to step 1:
9 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 9

Step 2:
The number 9 fits into 25 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 18 from 25 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 9

Moving on to step 3:
The number 9 fits into 73 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 72 from 73 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 9

Going ahead to step 4:
The number 9 fits into 18 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 282.0
If we subtract 18 from 18, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 9

Going ahead to step 5:
The number 9 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 2820.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 9

Going ahead to step 6:
20 divided by 9 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 28202.0
If we subtract 18 from 20, 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.

Moving on to step 7:
20 divided by 9 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 28202.2
Subtract 18 from 20 to 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.

Going ahead to step 8:
The number 9 fits into 20 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 28202.22
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.

The final result is 28202.22 with a remainder of 0.002.
