489839 divided by 42 
We want to figure out the number of times 489839 can be divided by 42.

Let's proceed to step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 42

Going ahead to step 2:
The number 42 fits into 48 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 42 away from 48, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 42

Let's proceed to step 3:
42 can be fit into 69 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 42 from 69 leaves us with 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 42

Advancing to step 4:
42 goes into 278 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtract 252 from 278 to get 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 42

Step 5:
263 divided by 42 is 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 1166.0
Subtract 252 from 263 to get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 42

On to step 6:
When dividing 119 by 42, we get 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 11662.0
The remainder is 35 after subtracting 84 from 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
42 can be fit into 350 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 11662.8
Subtracting 336 from 350 leaves us 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.

Moving on to step 8:
42 can be fit into 140 3 times, resulting in a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 11662.83
If we take 126 away from 140, we end up 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.

Advancing to step 9:
The number 42 fits into 140 3 times, leaving a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 11662.833
Subtract 126 from 140 to 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.

In conclusion, the division gives 11662.833 with a balance of 0.0014.
