We look at the division of 878188 by 1 
We want to divide 878188 by 1.

Step 1:
When dividing 8 by 1, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 8 from 8, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

On to step 2:
The number 1 fits into 7 7 times, leaving 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.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

On to step 3:
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: 878.0
Subtract 8 from 8 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Let's proceed to step 4:
When dividing 1 by 1, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 8781.0
Subtracting 1 from 1 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

On to step 5:
1 goes into 8 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 87818.0
If we subtract 8 from 8, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Let's proceed to step 6:
If we divide 8 by 1, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 878188.0
Deduct 8 from 8 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.

On to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 878188.0
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.

On to step 8:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 878188.0
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 878188.0 with a remainder of 0.0.
