We're dividing 665059 by 1 
We're looking to find how many times 1 goes into 665059.

On to step 1:
If we divide 6 by 1, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

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.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Moving on to step 3:
1 goes into 5 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 665.0
If we subtract 5 from 5, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Advancing to step 4:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6650.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Step 5:
If we divide 5 by 1, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 66505.0
The remainder is 0 after subtracting 5 from 5.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Step 6:
9 divided by 1 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 665059.0
Deduct 9 from 9 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.

On to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 665059.0
Subtracting 0 from 0 leaves us 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.

Step 8:
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: 665059.0
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 quotient of the division is 665059.0, and the remainder is 0.0.
