Let's divide 78863 by 90
We want to divide 78863 by 90.

On to step 1:
When dividing 7 by 90, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 90

On to step 2:
90 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 90

Step 3:
90 can be fit into 788 8 times, resulting in a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 720 away from 788, we end up with 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 90

Step 4:
If we divide 686 by 90, we get 7 and a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Deduct 630 from 686 and we're left with 56.
Include the next digit (3) from the dividend after 56, then repeat: 563 / 90

Step 5:
90 goes into 563 6 times with a remainder of 23.
The next digit of our result is 6. 
Result so far: 876.0
Subtract 540 from 563 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 6:
90 can be fit into 230 2 times, resulting in a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 876.2
If we subtract 180 from 230, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
If we divide 500 by 90, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 876.25
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 876.255
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 876.255 with a remaining 0.005.
