We look at the division of 887878 by 9 
Let's see how many times 9 fits into 887878.

Going ahead to step 1:
9 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 9

On to step 2:
9 goes into 88 9 times with a remainder of 7.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 81 from 88 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 9

On to step 3:
When dividing 77 by 9, we get 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 98.0
Subtract 72 from 77 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 9

On to step 4:
If we divide 58 by 9, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 986.0
Subtract 54 from 58 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 9

Advancing to step 5:
47 divided by 9 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 9865.0
Deduct 45 from 47 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 9

Let's proceed to step 6:
If we divide 28 by 9, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 98653.0
Deduct 27 from 28 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 9, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 98653.1
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
10 divided by 9 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 98653.11
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 98653.11 and a remainder of 0.001.
