We divide 878807 by 1
We're looking to find how many times 1 goes into 878807.

Step 1:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
If we take 8 away from 8, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Advancing to step 2:
1 goes into 7 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we take 7 away from 7, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Let's proceed to step 3:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 878.0
Subtract 8 from 8 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Going ahead to step 4:
If we divide 8 by 1, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8788.0
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 5:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 87880.0
Subtract 0 from 0 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Advancing to step 6:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 878807.0
If we subtract 7 from 7, 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 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 878807.0
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:
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: 878807.0
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.

The final result is 878807.0 with a remainder of 0.0.
