312779 ÷ 17 
We want to figure out the number of times 312779 can be divided by 17.

Step 1:
17 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 17

Let's proceed to step 2:
31 divided by 17 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 17 from 31 to get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 17

Let's proceed to step 3:
142 divided by 17 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 6 after subtracting 136 from 142.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 17

Advancing to step 4:
17 can be fit into 67 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 183.0
Subtracting 51 from 67 leaves us with 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 17

Let's proceed to step 5:
17 goes into 167 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 1839.0
If we subtract 153 from 167, we get 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 17

Going ahead to step 6:
If we divide 149 by 17, we get 8 and a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 18398.0
Deduct 136 from 149 and we're left 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.

Moving on to step 7:
If we divide 130 by 17, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 18398.7
If we subtract 119 from 130, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
The number 17 fits into 110 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 18398.76
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
The number 17 fits into 80 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 18398.764
If we take 68 away from 80, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
If we divide 120 by 17, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 18398.7647
Deduct 119 from 120 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
When dividing 10 by 17, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 18398.7647
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
100 divided by 17 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 18398.764705
Deduct 85 from 100 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.

Going ahead to step 13:
150 divided by 17 is 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 18398.7647058
Subtract 136 from 150 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
17 can be fit into 140 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 18398.76470588
If we take 136 away from 140, we end up 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.

After the division, we end up with 18398.76470588 and a remainder of 4e-09.
