We look at the division of 128860 by 45 
Our goal is to divide 128860 by 45.

On to step 1:
The number 45 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 45

Advancing to step 2:
45 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 45

Let's proceed to step 3:
The number 45 fits into 128 2 times, leaving a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 38 after subtracting 90 from 128.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 45

Moving on to step 4:
45 can be fit into 388 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 28 after subtracting 360 from 388.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 45

Moving on to step 5:
The number 45 fits into 286 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
If we subtract 270 from 286, we get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 45

Going ahead to step 6:
160 divided by 45 is 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 2863.0
Subtract 135 from 160 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2863.5
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
45 can be fit into 250 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2863.55
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 2863.55, and the remainder is 0.025.
