We look at the division of 807309 by 1 
We want to divide 807309 by 1.

Going ahead to step 1:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 8 from 8 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 2:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtract 0 from 0 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

On to step 3:
1 goes into 7 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 807.0
Subtracting 7 from 7 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Advancing to step 4:
If we divide 3 by 1, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 8073.0
If we take 3 away from 3, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

On to step 5:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 80730.0
Subtracting 0 from 0 leaves us with 0.
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.
The number 9 becomes the next digit in our result. 
Result so far: 807309.0
If we take 9 away from 9, 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.

Moving on to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 807309.0
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.

Advancing to step 8:
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: 807309.0
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 quotient of the division is 807309.0, and the remainder is 0.0.
