We're dividing 427209 by 17 
Our goal is to divide 427209 by 17.

Moving on to step 1:
17 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 17

Going ahead to step 2:
17 can be fit into 42 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 34 from 42 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 17

Advancing to step 3:
The number 17 fits into 87 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 85 away from 87, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 17

Going ahead to step 4:
When dividing 22 by 17, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
If we subtract 17 from 22, we get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 17

Let's proceed to step 5:
If we divide 50 by 17, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2512.0
The remainder is 16 after subtracting 34 from 50.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 17

Step 6:
If we divide 169 by 17, we get 9 and a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 25129.0
Deduct 153 from 169 and we're left 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.

Going ahead to step 7:
If we divide 160 by 17, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 25129.9
If we subtract 153 from 160, we 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.

Advancing to step 8:
17 goes into 70 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 25129.94
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:
When dividing 20 by 17, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 25129.941
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.

Step 10:
30 divided by 17 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 25129.9411
Subtract 17 from 30 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 25129.9411 and a remainder of 0.00013.
