We're dividing 215681 by 15 
We're looking to find how many times 15 goes into 215681.

Going ahead to step 1:
The number 15 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 15

On to step 2:
15 goes into 21 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 15 from 21 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 15

Step 3:
If we divide 65 by 15, we get 4 and a remainder of 5.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 60 from 65, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 15

Step 4:
15 can be fit into 56 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
If we subtract 45 from 56, we get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 15

Step 5:
The number 15 fits into 118 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 1437.0
Deduct 105 from 118 and we're left with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 15

Let's proceed to step 6:
15 can be fit into 131 8 times, resulting in a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 14378.0
If we take 120 away from 131, we end up 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.

Step 7:
15 goes into 110 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 14378.7
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 14378.73
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 14378.733
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 14378.733 and a remainder of 0.0005.
