We're dividing 433879 by 17 
Let's see how many times 17 fits into 433879.

Step 1:
If we divide 4 by 17, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 17

On to step 2:
43 divided by 17 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 34 from 43 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 17

Step 3:
17 goes into 93 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 85 from 93, we get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 17

Advancing to step 4:
17 goes into 88 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 255.0
Subtracting 85 from 88 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 17

Advancing to step 5:
17 can be fit into 37 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2552.0
Subtract 34 from 37 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 17

Going ahead to step 6:
39 divided by 17 is 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 25522.0
Deduct 34 from 39 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
17 can be fit into 50 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 25522.2
If we take 34 away from 50, we end up 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 8:
17 goes into 160 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 25522.29
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.

Going ahead to step 9:
The number 17 fits into 70 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 25522.294
The remainder is 2 after subtracting 68 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
17 goes into 20 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 25522.2941
Subtracting 17 from 20 leaves us 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 11:
17 goes into 30 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 25522.29411
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.

The final outcome is 25522.29411, with a leftover of 1.3e-05.
