128700 divided by 3 
We want to figure out the number of times 128700 can be divided by 3.

Advancing to step 1:
1 divided by 3 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

On to step 2:
When dividing 12 by 3, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 0 after subtracting 12 from 12.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Let's proceed to 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 take 6 away from 8, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Moving on to step 4:
If we divide 27 by 3, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 429.0
Subtracting 27 from 27 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Step 5:
3 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4290.0
If we take 0 away from 0, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Let's proceed to step 6:
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: 42900.0
The remainder is 0 after subtracting 0 from 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 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 42900.0
Subtract 0 from 0 to get 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:
If we divide 0 by 3, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42900.0
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 42900.0, with a leftover of 0.0.
