We're dividing 571878 by 1 
We want to figure out the number of times 571878 can be divided by 1.

Advancing to step 1:
The number 1 fits into 5 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 5 from 5 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

Let's proceed to step 2:
If we divide 7 by 1, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we take 7 away from 7, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Going ahead to step 3:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 571.0
If we subtract 1 from 1, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

On to step 4:
When dividing 8 by 1, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 5718.0
Subtract 8 from 8 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Going ahead to step 5:
If we divide 7 by 1, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 57187.0
The remainder is 0 after subtracting 7 from 7.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Going ahead to step 6:
When dividing 8 by 1, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 571878.0
The remainder is 0 after subtracting 8 from 8.
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:
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: 571878.0
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.

Step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 571878.0
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.

The final outcome is 571878.0, with a leftover of 0.0.
