We divide 450588 by 48
Let's see how many times 48 fits into 450588.

On to step 1:
If we divide 4 by 48, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 48

Step 2:
When dividing 45 by 48, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 48

On to step 3:
48 goes into 450 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 432 from 450 and we're left with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 48

Step 4:
48 can be fit into 185 3 times, resulting in a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 93.0
The remainder is 41 after subtracting 144 from 185.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 48

Going ahead to step 5:
48 goes into 418 8 times with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 938.0
Subtract 384 from 418 to get 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 48

On to step 6:
The number 48 fits into 348 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 9387.0
The remainder is 12 after subtracting 336 from 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
The number 48 fits into 120 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 9387.2
Deduct 96 from 120 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
240 divided by 48 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9387.25
If we subtract 240 from 240, 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.

Step 9:
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: 9387.25
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.

On to step 10:
48 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9387.25
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.

The final outcome is 9387.25, with a leftover of 0.0.
