380817 ÷ 3 
Let's see how many times 3 fits into 380817.

Step 1:
3 divided by 3 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 3 from 3 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 3

Going ahead to step 2:
8 divided by 3 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 6 from 8, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 3

Advancing to step 3:
20 divided by 3 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 126.0
The remainder is 2 after subtracting 18 from 20.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 3

Advancing to step 4:
28 divided by 3 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 1269.0
If we take 27 away from 28, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

Step 5:
When dividing 11 by 3, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 12693.0
Subtracting 9 from 11 leaves us with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

On to step 6:
If we divide 27 by 3, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 126939.0
If we take 27 away from 27, 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.

Step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 126939.0
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.

Advancing to step 8:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 126939.0
Deduct 0 from 0 and we're left 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 outcome is 126939.0, with a leftover of 0.0.
