397465 divided by 3 
Let's see how many times 3 fits into 397465.

On to step 1:
If we divide 3 by 3, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

On to step 2:
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: 13.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

Going ahead to step 3:
7 divided by 3 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 132.0
Deduct 6 from 7 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

On to step 4:
The number 3 fits into 14 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1324.0
Subtract 12 from 14 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Going ahead to step 5:
If we divide 26 by 3, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 13248.0
If we take 24 away from 26, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Step 6:
When dividing 25 by 3, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 132488.0
If we subtract 24 from 25, 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.

Advancing to step 7:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 132488.3
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.

On to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 132488.33
If we subtract 9 from 10, 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.

The quotient of the division is 132488.33, and the remainder is 0.001.
