Let's divide 136151 by 9
The aim is to understand the frequency of 9 in 136151.

Moving on to step 1:
If we divide 1 by 9, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 9

Advancing to step 2:
9 goes into 13 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 4 after subtracting 9 from 13.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 9

Going ahead to step 3:
46 divided by 9 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 45 from 46 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 9

Advancing to step 4:
9 goes into 11 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
Subtract 9 from 11 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 9

On to step 5:
If we divide 25 by 9, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 1512.0
Subtract 18 from 25 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 9

Moving on to step 6:
When dividing 71 by 9, we get 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 15127.0
Subtracting 63 from 71 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
9 can be fit into 80 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 15127.8
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
80 divided by 9 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 15127.88
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 15127.88 with a remaining 0.008.
