164450 divided by 9 
The aim is to understand the frequency of 9 in 164450.

Advancing to step 1:
9 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 9

Advancing to step 2:
The number 9 fits into 16 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 9 from 16 and we're left with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 9

Advancing to step 3:
The number 9 fits into 74 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 72 away from 74, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 9

Moving on to step 4:
24 divided by 9 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 182.0
Deduct 18 from 24 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 9

Advancing to step 5:
65 divided by 9 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1827.0
If we take 63 away from 65, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 9

Moving on to step 6:
9 can be fit into 20 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 18272.0
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.

On to step 7:
If we divide 20 by 9, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 18272.2
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.

Moving on to step 8:
9 can be fit into 20 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 18272.22
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 18272.22 and a remainder of 0.002.
