We're dividing 284439 by 10 
We want to figure out the number of times 284439 can be divided by 10.

Step 1:
The number 10 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 10

On to step 2:
10 goes into 28 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 20 from 28 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 10

Step 3:
10 can be fit into 84 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtracting 80 from 84 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 10

Moving on to step 4:
10 goes into 44 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 284.0
If we take 40 away from 44, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 10

On to step 5:
10 goes into 43 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 2844.0
If we subtract 40 from 43, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 10

On to step 6:
10 goes into 39 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 28443.0
If we take 30 away from 39, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 10 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 28443.9
Deduct 90 from 90 and we're left 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.

On to step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28443.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28443.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 28443.9, and the remainder is 0.0.
