397112 divided by 3 
Our goal is to divide 397112 by 3.

Moving on to step 1:
3 can be fit into 3 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
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

Step 2:
When dividing 9 by 3, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 9 from 9, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 3

On to step 3:
3 can be fit into 7 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 132.0
The remainder is 1 after subtracting 6 from 7.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

Going ahead to step 4:
The number 3 fits into 11 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 1323.0
Subtracting 9 from 11 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

On to step 5:
When dividing 21 by 3, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 13237.0
The remainder is 0 after subtracting 21 from 21.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 3

Advancing to step 6:
2 divided by 3 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 132370.0
Deduct 0 from 2 and we're left 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.

Advancing to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 132370.6
Subtract 18 from 20 to get 2.
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:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 132370.66
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 132370.66, with a leftover of 0.002.
