We're dividing 128460 by 30 
We want to figure out the number of times 128460 can be divided by 30.

Advancing to step 1:
1 divided by 30 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 30

Going ahead to step 2:
If we divide 12 by 30, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 30

Step 3:
If we divide 128 by 30, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 120 from 128, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 30

Step 4:
When dividing 84 by 30, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 60 from 84 and we're left with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 30

Going ahead to step 5:
30 goes into 246 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 428.0
If we take 240 away from 246, we end up with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 30

On to step 6:
30 can be fit into 60 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4282.0
Deduct 60 from 60 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.

Advancing to step 7:
0 divided by 30 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4282.0
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:
0 divided by 30 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4282.0
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.

Our division results in 4282.0 with a remaining 0.0.
