We divide 393906 by 3
We want to divide 393906 by 3.

Going ahead to step 1:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 3 from 3, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Moving on to step 2:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 9 from 9 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Advancing to step 3:
3 goes into 3 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 131.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Let's proceed to step 4:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 1313.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Step 5:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 13130.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 3

Advancing to step 6:
When dividing 6 by 3, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 131302.0
If we subtract 6 from 6, 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.

Advancing to step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 131302.0
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.

Going ahead to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 131302.0
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.

The final result is 131302.0 with a remainder of 0.0.
