We're dividing 426699 by 17 
We're looking to find how many times 17 goes into 426699.

Going ahead to step 1:
17 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 17

Step 2:
42 divided by 17 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 34 away from 42, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 17

On to step 3:
17 goes into 86 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 85 from 86 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 17

Advancing to step 4:
17 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
Subtracting 0 from 16 leaves us with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 17

Step 5:
169 divided by 17 is 9 with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 2509.0
Deduct 153 from 169 and we're left with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 17

Step 6:
17 goes into 169 9 times with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 25099.0
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.

On to step 7:
17 can be fit into 160 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 25099.9
Deduct 153 from 160 and we're left 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.

Let's proceed to step 8:
The number 17 fits into 70 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 25099.94
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.

Moving on to step 9:
20 divided by 17 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 25099.941
Subtract 17 from 20 to 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.

Step 10:
30 divided by 17 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 25099.9411
Subtracting 17 from 30 leaves us 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.

After the division, we end up with 25099.9411 and a remainder of 0.00013.
