399389 ÷ 17 
Let's see how many times 17 fits into 399389.

Advancing to step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 17

Step 2:
39 divided by 17 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 34 from 39 to get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 17

On to step 3:
17 goes into 59 3 times with a remainder of 8.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 8 after subtracting 51 from 59.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 17

Going ahead to step 4:
When dividing 83 by 17, we get 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 234.0
If we subtract 68 from 83, we get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 17

Advancing to step 5:
If we divide 158 by 17, we get 9 and a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 2349.0
The remainder is 5 after subtracting 153 from 158.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 17

Let's proceed to step 6:
If we divide 59 by 17, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 23493.0
Subtracting 51 from 59 leaves us 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.

Moving on to step 7:
If we divide 80 by 17, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 23493.4
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
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: 23493.47
If we subtract 119 from 120, we 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.

Moving on to step 9:
10 divided by 17 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 23493.47
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.

Going ahead to step 10:
The number 17 fits into 100 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 23493.4705
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.

Going ahead to step 11:
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: 23493.47058
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.

Step 12:
The number 17 fits into 140 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 23493.470588
If we subtract 136 from 140, we get 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 quotient of the division is 23493.470588, and the remainder is 4e-07.
