Let's divide 212057 by 17
Let's see how many times 17 fits into 212057.

Moving on to step 1:
The number 17 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of 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:
17 can be fit into 21 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 17 from 21, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 17

Advancing to step 3:
When dividing 42 by 17, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 8 after subtracting 34 from 42.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 17

Let's proceed to step 4:
17 goes into 80 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Deduct 68 from 80 and we're left with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 17

Let's proceed to step 5:
When dividing 125 by 17, we get 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 1247.0
The remainder is 6 after subtracting 119 from 125.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 17

Advancing to step 6:
If we divide 67 by 17, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 12473.0
Subtracting 51 from 67 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.

On to step 7:
When dividing 160 by 17, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 12473.9
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
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: 12473.94
Deduct 68 from 70 and we're left 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 9:
17 can be fit into 20 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 12473.941
Deduct 17 from 20 and we're left 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.

On to step 10:
When dividing 30 by 17, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 12473.9411
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 result is 12473.9411 with a remainder of 0.00013.
