128756 ÷ 3 
We want to divide 128756 by 3.

Moving on to step 1:
If we divide 1 by 3, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Moving on to step 2:
If we divide 12 by 3, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 12 from 12 to get 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.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 6 from 8, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Step 4:
3 can be fit into 27 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 429.0
If we take 27 away from 27, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Advancing to step 5:
If we divide 5 by 3, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 4291.0
Subtract 3 from 5 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Going ahead to step 6:
3 goes into 26 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 42918.0
If we subtract 24 from 26, 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.

Let's proceed to step 7:
3 goes into 20 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 42918.6
Subtracting 18 from 20 leaves us 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.

Moving on to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 42918.66
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.

The final outcome is 42918.66, with a leftover of 0.002.
