Let's divide 407848 by 3
Our goal is to divide 407848 by 3.

On to step 1:
3 goes into 4 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 3 from 4 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

Step 2:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 9 from 10, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 3

Let's proceed to step 3:
3 can be fit into 17 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 135.0
If we take 15 away from 17, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 3

Step 4:
28 divided by 3 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 1359.0
Subtracting 27 from 28 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

Advancing to step 5:
The number 3 fits into 14 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 13594.0
Subtract 12 from 14 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 3

Going ahead to step 6:
The number 3 fits into 28 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 135949.0
Deduct 27 from 28 and we're left 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.

On to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 135949.3
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.

Step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 135949.33
The remainder is 1 after subtracting 9 from 10.
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 outcome is 135949.33, with a leftover of 0.001.
