393925 divided by 3 
We want to divide 393925 by 3.

Going ahead to step 1:
If we divide 3 by 3, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 3 from 3, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

Let's proceed to step 2:
If we divide 9 by 3, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 9 away from 9, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Advancing to step 3:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Deduct 3 from 3 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Advancing to step 4:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 1313.0
Subtract 9 from 9 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 3

On to step 5:
When dividing 2 by 3, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 13130.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

On to step 6:
The number 3 fits into 25 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 131308.0
Deduct 24 from 25 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.

Let's proceed to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 131308.3
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.

Advancing to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 131308.33
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.

Our division results in 131308.33 with a remaining 0.001.
