183161 ÷ 18 
The aim is to understand the frequency of 18 in 183161.

Advancing to step 1:
18 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 18

Advancing to step 2:
When dividing 18 by 18, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 18 from 18 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 18

On to step 3:
When dividing 3 by 18, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 18

Advancing to step 4:
31 divided by 18 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Deduct 18 from 31 and we're left with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 18

On to step 5:
18 can be fit into 136 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 1017.0
Subtracting 126 from 136 leaves us with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 18

Let's proceed to step 6:
18 goes into 101 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 10175.0
Deduct 90 from 101 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
110 divided by 18 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 10175.6
If we take 108 away from 110, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
18 goes into 20 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 10175.61
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
18 can be fit into 20 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 10175.611
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 10175.611 with a remainder of 0.0002.
