We're dividing 798241 by 90 
Let's see how many times 90 fits into 798241.

Let's proceed to step 1:
90 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 90

Moving on to step 2:
When dividing 79 by 90, we get 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 90

On to step 3:
90 goes into 798 8 times with a remainder of 78.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 720 from 798 to get 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 90

Moving on to step 4:
782 divided by 90 is 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Deduct 720 from 782 and we're left with 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 90

Advancing to step 5:
90 goes into 624 6 times with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 886.0
If we take 540 away from 624, we end up with 84.
Grab the next digit (1) from the dividend, add it to 84, then carry on: 841 / 90

On to step 6:
90 can be fit into 841 9 times, resulting in a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 8869.0
Subtracting 810 from 841 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
The number 90 fits into 310 3 times, leaving a remainder of 40.
The next digit of our result is 3. 
Result so far: 8869.3
Deduct 270 from 310 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
When dividing 400 by 90, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 8869.34
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 8869.344
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 8869.344 and a remainder of 0.004.
