We're dividing 878556 by 1 
We want to figure out the number of times 878556 can be divided by 1.

Advancing to step 1:
8 divided by 1 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 8 from 8 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Going ahead to step 2:
7 divided by 1 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 87.0
Deduct 7 from 7 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Going ahead to step 3:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 878.0
If we subtract 8 from 8, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Let's proceed to step 4:
1 goes into 5 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8785.0
If we subtract 5 from 5, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Going ahead to step 5:
If we divide 5 by 1, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 87855.0
Subtract 5 from 5 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Moving on to step 6:
The number 1 fits into 6 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 878556.0
If we subtract 6 from 6, 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.

Let's proceed to step 7:
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: 878556.0
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.

On to step 8:
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: 878556.0
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 878556.0, and the remainder is 0.0.
