154723 ÷ 9 
The aim is to understand the frequency of 9 in 154723.

On to step 1:
9 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 9

Let's proceed to step 2:
15 divided by 9 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 9 from 15 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 9

Moving on to step 3:
9 goes into 64 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 63 from 64 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 9

Moving on to step 4:
17 divided by 9 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Subtract 9 from 17 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 9

Let's proceed to step 5:
9 goes into 82 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 1719.0
If we subtract 81 from 82, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 9

Going ahead to step 6:
If we divide 13 by 9, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 17191.0
Deduct 9 from 13 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.

On to step 7:
40 divided by 9 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 17191.4
If we take 36 away from 40, we end up 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.

Let's proceed to step 8:
The number 9 fits into 40 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 17191.44
If we take 36 away from 40, we end up 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.

Our division results in 17191.44 with a remaining 0.004.
