423985 ÷ 17 
We're looking to find how many times 17 goes into 423985.

Going ahead to step 1:
4 divided by 17 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 17

Let's proceed to step 2:
If we divide 42 by 17, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 8 after subtracting 34 from 42.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 17

Going ahead to step 3:
The number 17 fits into 83 4 times, leaving a remainder of 15.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 15 after subtracting 68 from 83.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 17

Going ahead to step 4:
17 goes into 159 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 249.0
If we subtract 153 from 159, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 17

Let's proceed to step 5:
68 divided by 17 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 2494.0
The remainder is 0 after subtracting 68 from 68.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 17

Step 6:
17 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 24940.0
Subtract 0 from 5 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
50 divided by 17 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 24940.2
Subtracting 34 from 50 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.

Step 8:
17 can be fit into 160 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 24940.29
If we take 153 away from 160, we end up 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:
17 can be fit into 70 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 24940.294
If we subtract 68 from 70, we get 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 10:
The number 17 fits into 20 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 24940.2941
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.

Let's proceed to step 11:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 24940.29411
If we subtract 17 from 30, we 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 quotient of the division is 24940.29411, and the remainder is 1.3e-05.
