Let's divide 39039 by 42
We want to divide 39039 by 42.

Advancing to step 1:
3 divided by 42 is 0 with 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.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 42

Going ahead to step 2:
39 divided by 42 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 42

On to step 3:
390 divided by 42 is 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 12 after subtracting 378 from 390.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 42

Going ahead to step 4:
42 can be fit into 123 2 times, resulting in a remainder of 39.
The next digit of our result is 2. 
Result so far: 92.0
Subtracting 84 from 123 leaves us with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 42

Moving on to step 5:
The number 42 fits into 399 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 929.0
The remainder is 21 after subtracting 378 from 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 6:
The number 42 fits into 210 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 929.5
The remainder is 0 after subtracting 210 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
When dividing 0 by 42, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 929.5
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.

Step 8:
0 divided by 42 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 929.5
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 929.5 with a balance of 0.0.
