186072 ÷ 9 
The aim is to understand the frequency of 9 in 186072.

On to step 1:
The number 9 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 9

Let's proceed to step 2:
18 divided by 9 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 18 from 18, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 9

Advancing to step 3:
6 divided by 9 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 6, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 9

Advancing to step 4:
If we divide 60 by 9, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 206.0
Deduct 54 from 60 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 9

Advancing to step 5:
67 divided by 9 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 2067.0
Deduct 63 from 67 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 9

On to step 6:
9 can be fit into 42 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 20674.0
Deduct 36 from 42 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.

On to step 7:
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: 20674.6
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.

Moving on to step 8:
9 goes into 60 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 20674.66
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.

The final result is 20674.66 with a remainder of 0.006.
