216004 divided by 15 
We want to divide 216004 by 15.

Step 1:
15 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 15

Advancing to step 2:
When dividing 21 by 15, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 6 after subtracting 15 from 21.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 15

Let's proceed to step 3:
15 can be fit into 66 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 60 from 66 and we're left with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 15

Let's proceed to step 4:
When dividing 60 by 15, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
Subtracting 60 from 60 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 15

Going ahead to step 5:
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: 1440.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 15

Moving on to step 6:
The number 15 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 14400.0
If we take 0 away from 4, we end up 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 can be fit into 40 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 14400.2
Subtract 30 from 40 to 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.

Let's proceed to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 14400.26
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.

Going ahead to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 14400.266
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.

The final result is 14400.266 with a remainder of 0.001.
