We divide 156624 by 9
The aim is to understand the frequency of 9 in 156624.

On to step 1:
9 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 9

On to step 2:
The number 9 fits into 15 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 9 from 15, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 9

Moving on to step 3:
When dividing 66 by 9, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 63 from 66 and we're left with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 9

Moving on to step 4:
9 goes into 36 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 174.0
If we take 36 away from 36, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 9

Going ahead to step 5:
When dividing 2 by 9, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 1740.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 9

Going ahead to step 6:
9 can be fit into 24 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 17402.0
Subtracting 18 from 24 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
The number 9 fits into 60 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 17402.6
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 17402.66
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 17402.66 with a remaining 0.006.
