We look at the division of 404409 by 48 
Let's see how many times 48 fits into 404409.

Step 1:
When dividing 4 by 48, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 48

Advancing to step 2:
48 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 48

Going ahead to step 3:
When dividing 404 by 48, we get 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 20 after subtracting 384 from 404.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 48

Advancing to step 4:
The number 48 fits into 204 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 12 after subtracting 192 from 204.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 48

Advancing to step 5:
120 divided by 48 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 842.0
If we take 96 away from 120, we end up with 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 48

Advancing to step 6:
249 divided by 48 is 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 8425.0
If we subtract 240 from 249, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
48 can be fit into 90 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 8425.1
Subtracting 48 from 90 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
The number 48 fits into 420 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 8425.18
Subtract 384 from 420 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
48 can be fit into 360 7 times, resulting in a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 8425.187
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
48 goes into 240 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8425.1875
The remainder is 0 after subtracting 240 from 240.
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 11:
48 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8425.1875
Deduct 0 from 0 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 12:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8425.1875
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.

The final result is 8425.1875 with a remainder of 0.0.
