We divide 312424 by 17
We want to divide 312424 by 17.

Step 1:
If we divide 3 by 17, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 17

Step 2:
If we divide 31 by 17, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 17 from 31 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 17

Let's proceed to step 3:
142 divided by 17 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 136 from 142, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 17

Moving on to step 4:
If we divide 64 by 17, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
Deduct 51 from 64 and we're left with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 17

Step 5:
When dividing 132 by 17, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 1837.0
Deduct 119 from 132 and we're left with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 17

Moving on to step 6:
The number 17 fits into 134 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 18377.0
Subtract 119 from 134 to get 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:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 18377.8
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.

Step 8:
17 goes into 140 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 18377.88
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 18377.88 and a remainder of 0.004.
