We're dividing 844366 by 90 
Let's see how many times 90 fits into 844366.

Going ahead to step 1:
When dividing 8 by 90, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 90

Step 2:
The number 90 fits into 84 0 times, leaving a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 90

Going ahead to step 3:
If we divide 844 by 90, we get 9 and a remainder of 34.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 810 from 844, we get 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 90

Step 4:
When dividing 343 by 90, we get 3 with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 93.0
The remainder is 73 after subtracting 270 from 343.
Take the next digit (6) from the dividend and append it to 73, then repeat: 736 / 90

On to step 5:
If we divide 736 by 90, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 938.0
Subtracting 720 from 736 leaves us with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 90

Going ahead to step 6:
90 goes into 166 1 times with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 9381.0
Subtracting 90 from 166 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 7:
The number 90 fits into 760 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 9381.8
Subtracting 720 from 760 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.

On to step 8:
400 divided by 90 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 9381.84
The remainder is 40 after subtracting 360 from 400.
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 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 9381.844
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 9381.844, and the remainder is 0.004.
