We divide 665906 by 1
Let's see how many times 1 fits into 665906.

On to step 1:
6 divided by 1 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 6 from 6 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Let's proceed to step 2:
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: 66.0
Subtract 6 from 6 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Going ahead to step 3:
5 divided by 1 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 665.0
If we subtract 5 from 5, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Moving on to step 4:
9 divided by 1 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 6659.0
Deduct 9 from 9 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Going ahead to step 5:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 66590.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Advancing to step 6:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 665906.0
If we subtract 6 from 6, 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 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 665906.0
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.

Advancing to step 8:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 665906.0
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.

The final result is 665906.0 with a remainder of 0.0.
