We look at the division of 807570 by 1 
We want to figure out the number of times 807570 can be divided by 1.

Let's proceed to step 1:
1 goes into 8 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 8 from 8, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Going ahead to step 2:
1 can be fit into 0 0 times, resulting in 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 (7) from the dividend to 0 and continue with: 7 / 1

Step 3:
1 can be fit into 7 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 807.0
Deduct 7 from 7 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Going ahead to step 4:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8075.0
Subtracting 5 from 5 leaves us with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Advancing to step 5:
When dividing 7 by 1, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 80757.0
If we take 7 away from 7, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Let's proceed to step 6:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 807570.0
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.

Going ahead to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 807570.0
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.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 807570.0
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.

The final result is 807570.0 with a remainder of 0.0.
