809670 ÷ 1 
Our goal is to divide 809670 by 1.

On to step 1:
1 goes into 8 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 8 from 8 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Moving on to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtract 0 from 0 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

On to step 3:
9 divided by 1 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 809.0
If we take 9 away from 9, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Advancing to step 4:
1 goes into 6 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 8096.0
Subtract 6 from 6 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Step 5:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 80967.0
Subtract 7 from 7 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Step 6:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 809670.0
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.

On to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 809670.0
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.

Advancing to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 809670.0
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.

The final outcome is 809670.0, with a leftover of 0.0.
