39842 ÷ 17 
We want to divide 39842 by 17.

Step 1:
If we divide 3 by 17, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 17

Advancing to step 2:
When dividing 39 by 17, we get 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
If we take 34 away from 39, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 17

Let's proceed to step 3:
17 goes into 58 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 51 from 58 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 17

Step 4:
17 goes into 74 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 234.0
Subtract 68 from 74 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 17

On to step 5:
17 goes into 62 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 2343.0
Deduct 51 from 62 and we're left 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.

Advancing to step 6:
The number 17 fits into 110 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 2343.6
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.

Let's proceed to step 7:
17 goes into 80 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 2343.64
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.

Advancing to step 8:
If we divide 120 by 17, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 2343.647
If we take 119 away from 120, we end up 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.

Let's proceed to step 9:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2343.647
Subtracting 0 from 10 leaves us 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.

On to step 10:
When dividing 100 by 17, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2343.64705
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 11:
17 goes into 150 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 2343.647058
Deduct 136 from 150 and we're left 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 12:
The number 17 fits into 140 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 2343.6470588
Subtract 136 from 140 to 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 final result is 2343.6470588 with a remainder of 4e-08.
