We're dividing 148983 by 9 
The aim is to understand the frequency of 9 in 148983.

On to step 1:
The number 9 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 9

Moving on to step 2:
14 divided by 9 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 5 after subtracting 9 from 14.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 9

On to step 3:
58 divided by 9 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 54 away from 58, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 9

Advancing to step 4:
The number 9 fits into 49 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 165.0
Subtract 45 from 49 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 9

Going ahead to step 5:
9 can be fit into 48 5 times, resulting in a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 1655.0
If we subtract 45 from 48, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 9

On to step 6:
The number 9 fits into 33 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 16553.0
Deduct 27 from 33 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 7:
9 goes into 60 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 16553.6
Subtracting 54 from 60 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.

Advancing to step 8:
9 goes into 60 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 16553.66
If we subtract 54 from 60, we get 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 16553.66 and a remainder of 0.006.
