156651 divided by 9 
The aim is to understand the frequency of 9 in 156651.

Let's proceed to step 1:
When dividing 1 by 9, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 9

Advancing to step 2:
15 divided by 9 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 9 from 15 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 9

Advancing to step 3:
66 divided by 9 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 63 from 66, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 9

Moving on to step 4:
9 goes into 36 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 174.0
If we take 36 away from 36, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 9

Moving on to step 5:
If we divide 5 by 9, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 1740.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 9

Step 6:
If we divide 51 by 9, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 17405.0
If we take 45 away from 51, 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.

Going ahead to step 7:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 17405.6
Deduct 54 from 60 and we're left 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.

Advancing to step 8:
When dividing 60 by 9, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 17405.66
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.

After the division, we end up with 17405.66 and a remainder of 0.006.
