Let's divide 338871 by 3
Our goal is to divide 338871 by 3.

Moving on to step 1:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 3 from 3 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

On to step 2:
3 goes into 3 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 3 away from 3, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Step 3:
3 goes into 8 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Subtracting 6 from 8 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Let's proceed to step 4:
When dividing 28 by 3, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1129.0
If we subtract 27 from 28, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

On to step 5:
If we divide 17 by 3, we get 5 and a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 11295.0
If we take 15 away from 17, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Let's proceed to step 6:
When dividing 21 by 3, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 112957.0
Subtracting 21 from 21 leaves us 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.

Moving on to step 7:
0 divided by 3 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 112957.0
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.

Let's proceed to step 8:
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: 112957.0
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 outcome is 112957.0, with a leftover of 0.0.
