We divide 434688 by 17
Let's see how many times 17 fits into 434688.

Advancing to step 1:
4 divided by 17 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 17

Step 2:
The number 17 fits into 43 2 times, leaving a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 34 from 43, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 17

Moving on to step 3:
If we divide 94 by 17, we get 5 and a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we subtract 85 from 94, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 17

Step 4:
The number 17 fits into 96 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 255.0
If we subtract 85 from 96, we get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 17

Going ahead to step 5:
If we divide 118 by 17, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 2556.0
Subtracting 102 from 118 leaves us with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 17

Going ahead to step 6:
The number 17 fits into 168 9 times, leaving a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 25569.0
Deduct 153 from 168 and we're left 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.

Moving on to step 7:
When dividing 150 by 17, we get 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 25569.8
Subtracting 136 from 150 leaves us 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.

Let's proceed to step 8:
When dividing 140 by 17, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 25569.88
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.

The final outcome is 25569.88, with a leftover of 0.004.
