419400 ÷ 48 
We're looking to find how many times 48 goes into 419400.

Step 1:
4 divided by 48 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 48

Let's proceed to step 2:
48 goes into 41 0 times with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 48

Step 3:
When dividing 419 by 48, we get 8 with a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 384 from 419 leaves us with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 48

On to step 4:
354 divided by 48 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 336 from 354 to get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 48

Going ahead to step 5:
48 can be fit into 180 3 times, resulting in a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 873.0
Subtract 144 from 180 to get 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 48

Advancing to step 6:
360 divided by 48 is 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 8737.0
Subtract 336 from 360 to 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.

On to step 7:
48 can be fit into 240 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 8737.5
Subtract 240 from 240 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.

On to step 8:
0 divided by 48 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8737.5
Subtracting 0 from 0 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.

Going ahead to step 9:
0 divided by 48 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8737.5
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.

After the division, we end up with 8737.5 and a remainder of 0.0.
