We divide 662159 by 9
The aim is to understand the frequency of 9 in 662159.

Going ahead to step 1:
9 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 9

Advancing to step 2:
The number 9 fits into 66 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 63 from 66 and we're left with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 9

Advancing to step 3:
The number 9 fits into 32 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we take 27 away from 32, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 9

Step 4:
When dividing 51 by 9, we get 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 735.0
Subtracting 45 from 51 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 9

On to step 5:
9 can be fit into 65 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7357.0
Deduct 63 from 65 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 9

Let's proceed to step 6:
29 divided by 9 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 73573.0
Deduct 27 from 29 and we're left 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.

Going ahead to step 7:
20 divided by 9 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 73573.2
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
9 can be fit into 20 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 73573.22
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.

The final result is 73573.22 with a remainder of 0.002.
