211865 ÷ 15 
We're looking to find how many times 15 goes into 211865.

Going ahead to step 1:
15 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 15

Step 2:
15 goes into 21 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 15 from 21, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 15

Moving on to step 3:
61 divided by 15 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 60 from 61 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 15

Moving on to step 4:
15 goes into 18 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 141.0
Subtracting 15 from 18 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 15

Step 5:
The number 15 fits into 36 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 1412.0
Subtracting 30 from 36 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 15

Moving on to step 6:
15 goes into 65 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 14124.0
If we take 60 away from 65, we end up 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 7:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 14124.3
Deduct 45 from 50 and we're left 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 8:
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: 14124.33
If we take 45 away from 50, we end up 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.

The final result is 14124.33 with a remainder of 0.005.
