We look at the division of 78254 by 90 
Our goal is to divide 78254 by 90.

Going ahead to step 1:
90 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 90

Step 2:
When dividing 78 by 90, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 90

Advancing to step 3:
782 divided by 90 is 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 720 from 782 and we're left with 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 90

Step 4:
90 goes into 625 6 times with a remainder of 85.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 540 from 625 leaves us with 85.
Bring next digit (4) of the dividend behind the 85 and repeat the process: 854 / 90

Going ahead to step 5:
854 divided by 90 is 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 869.0
If we subtract 810 from 854, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 6:
90 can be fit into 440 4 times, resulting in a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 869.4
Subtract 360 from 440 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 7:
When dividing 800 by 90, we get 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 869.48
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
90 goes into 800 8 times with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 869.488
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 869.488 with a remaining 0.008.
