We look at the division of 212685 by 17 
We're looking to find how many times 17 goes into 212685.

Moving on to step 1:
If we divide 2 by 17, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 17

Advancing to step 2:
17 can be fit into 21 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 17 from 21.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 17

Let's proceed to step 3:
When dividing 42 by 17, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 34 from 42 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 17

Going ahead to step 4:
When dividing 86 by 17, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtracting 85 from 86 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 17

Moving on to step 5:
The number 17 fits into 18 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1251.0
Deduct 17 from 18 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 17

On to step 6:
17 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 12510.0
If we take 0 away from 15, 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 7:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 12510.8
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
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: 12510.88
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.

After the division, we end up with 12510.88 and a remainder of 0.004.
