We're dividing 665860 by 1 
Our goal is to divide 665860 by 1.

Advancing to step 1:
If we divide 6 by 1, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 6 from 6, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

On to step 2:
If we divide 6 by 1, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we take 6 away from 6, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Let's proceed to step 3:
5 divided by 1 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 665.0
Deduct 5 from 5 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Step 4:
If we divide 8 by 1, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 6658.0
The remainder is 0 after subtracting 8 from 8.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Advancing to step 5:
6 divided by 1 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 66586.0
Subtracting 6 from 6 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Advancing to step 6:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 665860.0
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:
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: 665860.0
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.

On to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 665860.0
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.

Our division results in 665860.0 with a remaining 0.0.
