Let's divide 899392 by 9
The aim is to understand the frequency of 9 in 899392.

Advancing to step 1:
The number 9 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 9

Advancing to step 2:
9 goes into 89 9 times with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 8 after subtracting 81 from 89.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 9

Moving on to step 3:
If we divide 89 by 9, we get 9 and a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtracting 81 from 89 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 9

On to step 4:
9 can be fit into 83 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 999.0
The remainder is 2 after subtracting 81 from 83.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 9

Let's proceed to step 5:
The number 9 fits into 29 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 9993.0
If we subtract 27 from 29, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 9

Let's proceed to step 6:
When dividing 22 by 9, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 99932.0
Subtract 18 from 22 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.

Advancing to step 7:
40 divided by 9 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 99932.4
Deduct 36 from 40 and we're left 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 8:
9 goes into 40 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 99932.44
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.

The final outcome is 99932.44, with a leftover of 0.004.
