453864 divided by 48 
We're looking to find how many times 48 goes into 453864.

Step 1:
4 divided by 48 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 48

Step 2:
The number 48 fits into 45 0 times, leaving a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 48

Advancing to step 3:
The number 48 fits into 453 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 432 from 453, we get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 48

Moving on to step 4:
48 can be fit into 218 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtract 192 from 218 to get 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 48

On to step 5:
266 divided by 48 is 5 with a remainder of 26.
The next digit of our result is 5. 
Result so far: 945.0
If we subtract 240 from 266, we get 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 48

Moving on to step 6:
264 divided by 48 is 5 with a remainder of 24.
The next digit of our result is 5. 
Result so far: 9455.0
Subtract 240 from 264 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.

Let's proceed to step 7:
If we divide 240 by 48, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 9455.5
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.

Going ahead to step 8:
0 divided by 48 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9455.5
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.

Advancing to step 9:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9455.5
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.

The final outcome is 9455.5, with a leftover of 0.0.
