Let's divide 223987 by 17
We're looking to find how many times 17 goes into 223987.

Going ahead to step 1:
If we divide 2 by 17, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 17

Advancing to step 2:
22 divided by 17 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 17 from 22 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 17

On to step 3:
The number 17 fits into 53 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 51 from 53, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 17

Moving on to step 4:
The number 17 fits into 29 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Subtracting 17 from 29 leaves us with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 17

Step 5:
17 can be fit into 128 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 1317.0
If we take 119 away from 128, we end up with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 17

Moving on to step 6:
The number 17 fits into 97 5 times, leaving a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 13175.0
Deduct 85 from 97 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
If we divide 120 by 17, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 13175.7
If we take 119 away from 120, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
17 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 13175.7
If we take 0 away from 10, we end up 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.

Step 9:
If we divide 100 by 17, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 13175.705
If we take 85 away from 100, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 13175.7058
If we subtract 136 from 150, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
17 can be fit into 140 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 13175.70588
If we take 136 away from 140, 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.

The final outcome is 13175.70588, with a leftover of 4e-06.
