Let's divide 985963 by 90
We want to divide 985963 by 90.

Advancing to step 1:
90 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 90

On to step 2:
When dividing 98 by 90, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 90 away from 98, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 90

Going ahead to step 3:
When dividing 85 by 90, we get 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 85 leaves us with 85.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 90

On to step 4:
When dividing 859 by 90, we get 9 with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 109.0
The remainder is 49 after subtracting 810 from 859.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 90

On to step 5:
496 divided by 90 is 5 with a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 1095.0
If we take 450 away from 496, we end up with 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 90

Advancing to step 6:
90 can be fit into 463 5 times, resulting in a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 10955.0
Subtract 450 from 463 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
90 can be fit into 130 1 times, resulting in a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 10955.1
Deduct 90 from 130 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.

Let's proceed to step 8:
90 goes into 400 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 10955.14
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.

Step 9:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 10955.144
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 10955.144 and a remainder of 0.004.
