We're dividing 210699 by 17 
We're looking to find how many times 17 goes into 210699.

Step 1:
17 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our 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

Step 2:
17 goes into 21 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 17 from 21 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 17

Going ahead to step 3:
When dividing 40 by 17, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 6 after subtracting 34 from 40.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 17

On to step 4:
17 goes into 66 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtracting 51 from 66 leaves us with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 17

On to step 5:
The number 17 fits into 159 9 times, leaving a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 1239.0
If we subtract 153 from 159, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 17

Advancing to step 6:
When dividing 69 by 17, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 12394.0
Subtracting 68 from 69 leaves us 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.

On to step 7:
If we divide 10 by 17, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 12394.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 17 fits into 100 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 12394.05
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
The number 17 fits into 150 8 times, leaving a remainder of 14.
The next digit of our result is 8. 
Result so far: 12394.058
Subtract 136 from 150 to 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.

Step 10:
When dividing 140 by 17, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 12394.0588
Subtracting 136 from 140 leaves us 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.

In conclusion, the division gives 12394.0588 with a balance of 4e-05.
