We look at the division of 458848 by 3 
Let's see how many times 3 fits into 458848.

Advancing to step 1:
3 goes into 4 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 3 from 4 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Step 2:
15 divided by 3 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 0 after subtracting 15 from 15.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Step 3:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Deduct 6 from 8 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 3

Let's proceed to step 4:
The number 3 fits into 28 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1529.0
The remainder is 1 after subtracting 27 from 28.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

On to step 5:
14 divided by 3 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 15294.0
Deduct 12 from 14 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 3

Going ahead to step 6:
If we divide 28 by 3, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 152949.0
If we subtract 27 from 28, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 152949.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 152949.33
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 152949.33 with a remainder of 0.001.
