Let's divide 39842 by 80
We're looking to find how many times 80 goes into 39842.

Moving on to step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 80

Moving on to step 2:
80 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 80

Moving on to step 3:
80 can be fit into 398 4 times, resulting in a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 320 from 398 leaves us with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 80

Step 4:
If we divide 784 by 80, we get 9 and a remainder of 64.
The next digit of our result is 9. 
Result so far: 49.0
Deduct 720 from 784 and we're left with 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 80

Advancing to step 5:
80 goes into 642 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 498.0
Deduct 640 from 642 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 6:
The number 80 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 498.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
When dividing 200 by 80, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 498.02
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
80 goes into 400 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 498.025
Subtracting 400 from 400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 498.025
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 498.025
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 498.025 with a balance of 0.0.
