We look at the division of 448058 by 3 
Let's see how many times 3 fits into 448058.

Let's proceed to step 1:
When dividing 4 by 3, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

Going ahead to step 2:
If we divide 14 by 3, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 2 after subtracting 12 from 14.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 3

Step 3:
If we divide 28 by 3, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 149.0
Deduct 27 from 28 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

On to step 4:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1493.0
If we subtract 9 from 10, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

Let's proceed to step 5:
3 goes into 15 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 14935.0
Deduct 15 from 15 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

On to step 6:
If we divide 8 by 3, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 149352.0
The remainder is 2 after subtracting 6 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 149352.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 149352.66
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 149352.66 and a remainder of 0.002.
