We're dividing 878986 by 89 
Let's see how many times 89 fits into 878986.

Step 1:
When dividing 8 by 89, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 89

On to step 2:
89 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 89

Going ahead to step 3:
If we divide 878 by 89, we get 9 and a remainder of 77.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 801 away from 878, we end up with 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 89

Advancing to step 4:
When dividing 779 by 89, we get 8 with a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we subtract 712 from 779, we get 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 89

Moving on to step 5:
If we divide 678 by 89, we get 7 and a remainder of 55.
The next digit of our result is 7. 
Result so far: 987.0
Subtract 623 from 678 to get 55.
Fetch the next digit (6) from the dividend, attach it to 55 and continue: 556 / 89

Let's proceed to step 6:
89 goes into 556 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 9876.0
Subtract 534 from 556 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
89 can be fit into 220 2 times, resulting in a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 9876.2
Subtract 178 from 220 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
420 divided by 89 is 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 9876.24
Deduct 356 from 420 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
The number 89 fits into 640 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 9876.247
If we take 623 away from 640, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
170 divided by 89 is 1 with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 9876.2471
If we subtract 89 from 170, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 11:
89 can be fit into 810 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 9876.24719
Deduct 801 from 810 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
If we divide 90 by 89, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 9876.247191
Deduct 89 from 90 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 13:
89 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 9876.247191
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
When dividing 100 by 89, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 9876.24719101
If we subtract 89 from 100, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 9876.24719101 and a remainder of 1.1e-08.
