215885 ÷ 17 
Let's see how many times 17 fits into 215885.

Let's proceed to step 1:
17 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 17

Going ahead to step 2:
21 divided by 17 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 17 from 21, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 17

On to step 3:
The number 17 fits into 45 2 times, leaving a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 34 from 45 to get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 17

Advancing to step 4:
118 divided by 17 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we take 102 away from 118, we end up with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 17

Going ahead to step 5:
If we divide 168 by 17, we get 9 and a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 1269.0
If we take 153 away from 168, we end up with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 17

On to step 6:
The number 17 fits into 155 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 12699.0
If we take 153 away from 155, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 17, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 12699.1
Subtracting 17 from 20 leaves us with 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 8:
17 can be fit into 30 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 12699.11
Deduct 17 from 30 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 12699.11, with a leftover of 0.013.
