Let's divide 210566 by 17
We're looking to find how many times 17 goes into 210566.

On 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
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 17

Going ahead to step 2:
If we divide 21 by 17, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 17 from 21 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 17

Advancing to step 3:
40 divided by 17 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 34 from 40 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 17

Step 4:
The number 17 fits into 65 3 times, leaving a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Subtract 51 from 65 to get 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 17

Moving on to step 5:
17 can be fit into 146 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 1238.0
Subtract 136 from 146 to get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 17

Step 6:
When dividing 106 by 17, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 12386.0
If we subtract 102 from 106, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
17 goes into 40 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 12386.2
Subtract 34 from 40 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
17 can be fit into 60 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 12386.23
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
17 goes into 90 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 12386.235
If we take 85 away from 90, 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.

Advancing to step 10:
When dividing 50 by 17, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12386.2352
Subtracting 34 from 50 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
17 goes into 160 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 12386.23529
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
If we divide 70 by 17, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 12386.235294
If we subtract 68 from 70, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
17 can be fit into 20 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 12386.2352941
If we subtract 17 from 20, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
30 divided by 17 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 12386.23529411
If we take 17 away from 30, we end up 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 12386.23529411, with a leftover of 1.3e-08.
