We look at the division of 128746 by 1 
Our goal is to divide 128746 by 1.

Advancing to step 1:
1 divided by 1 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 1 away from 1, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Going ahead to step 2:
1 goes into 2 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 2 from 2 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Advancing to step 3:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 128.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Going ahead to step 4:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 1287.0
The remainder is 0 after subtracting 7 from 7.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Step 5:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 12874.0
Deduct 4 from 4 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

On to step 6:
6 divided by 1 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 128746.0
The remainder is 0 after subtracting 6 from 6.
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:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 128746.0
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.

Going ahead to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 128746.0
If we subtract 0 from 0, we 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.

The final result is 128746.0 with a remainder of 0.0.
