We look at the division of 488665 by 1 
We want to figure out the number of times 488665 can be divided by 1.

Advancing to step 1:
1 goes into 4 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 4 away from 4, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Moving on to step 2:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 48.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

On to step 3:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 488.0
If we subtract 8 from 8, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Moving on to step 4:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 4886.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

On to step 5:
When dividing 6 by 1, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 48866.0
If we subtract 6 from 6, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Advancing to step 6:
1 goes into 5 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 488665.0
If we subtract 5 from 5, 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.

Advancing to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 488665.0
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:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 488665.0
Deduct 0 from 0 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.

The final result is 488665.0 with a remainder of 0.0.
