18168 ÷ 15 
We're looking to find how many times 15 goes into 18168.

Moving on to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 15

Let's proceed to step 2:
15 goes into 18 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 15 from 18, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 15

Let's proceed to step 3:
The number 15 fits into 31 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 30 from 31 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 15

On to step 4:
15 goes into 16 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 121.0
Subtract 15 from 16 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 15

Going ahead to step 5:
When dividing 18 by 15, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1211.0
If we subtract 15 from 18, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 6:
The number 15 fits into 30 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 1211.2
Deduct 30 from 30 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.

Advancing to step 7:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1211.2
If we take 0 away from 0, we end up 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.

Going ahead to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1211.2
If we subtract 0 from 0, we 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.

After the division, we end up with 1211.2 and a remainder of 0.0.
