Let's divide 180724 by 15
We're looking to find how many times 15 goes into 180724.

Step 1:
1 divided by 15 is 0 with 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.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 15

Step 2:
The number 15 fits into 18 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 15 from 18 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 15

Going ahead to step 3:
15 can be fit into 30 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 30 from 30 leaves us with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 15

Going ahead to step 4:
When dividing 7 by 15, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 120.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 15

Going ahead to step 5:
When dividing 72 by 15, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 1204.0
If we subtract 60 from 72, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 15

On to step 6:
124 divided by 15 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 12048.0
Deduct 120 from 124 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
15 goes into 40 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 12048.2
If we subtract 30 from 40, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 12048.26
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
100 divided by 15 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 12048.266
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 12048.266, with a leftover of 0.001.
