173187 divided by 9 
The aim is to understand the frequency of 9 in 173187.

Step 1:
9 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 9

On to step 2:
If we divide 17 by 9, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 9 from 17 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 9

Let's proceed to step 3:
If we divide 83 by 9, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 81 from 83 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 9

Going ahead to step 4:
If we divide 21 by 9, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Subtract 18 from 21 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 9

On to step 5:
9 goes into 38 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 1924.0
Subtract 36 from 38 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 9

On to step 6:
9 can be fit into 27 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 19243.0
Subtract 27 from 27 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
When dividing 0 by 9, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19243.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 9 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19243.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 19243.0, and the remainder is 0.0.
