391071 ÷ 17 
We want to divide 391071 by 17.

Moving on to step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 17

Going ahead to step 2:
17 goes into 39 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 34 from 39 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 17

Advancing to step 3:
17 goes into 51 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 51 away from 51, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 17

On to step 4:
17 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 230.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 17

Step 5:
The number 17 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 2300.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 17

Going ahead to step 6:
The number 17 fits into 71 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 23004.0
Deduct 68 from 71 and we're left 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 7:
The number 17 fits into 30 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 23004.1
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.

Moving on to step 8:
17 can be fit into 130 7 times, resulting in a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 23004.17
If we take 119 away from 130, we end up with 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 9:
110 divided by 17 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 23004.176
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 17 fits into 80 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 23004.1764
Subtract 68 from 80 to get 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 11:
When dividing 120 by 17, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 23004.17647
Subtract 119 from 120 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
If we divide 10 by 17, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 23004.17647
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
100 divided by 17 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 23004.1764705
If we subtract 85 from 100, we 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 14:
150 divided by 17 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 23004.17647058
If we subtract 136 from 150, we 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.

The final outcome is 23004.17647058, with a leftover of 1.4e-08.
