We divide 803952 by 90
We want to divide 803952 by 90.

Let's proceed to step 1:
8 divided by 90 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 90

Going ahead to step 2:
90 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 90

Step 3:
When dividing 803 by 90, we get 8 with a remainder of 83.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 720 from 803, we get 83.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 90

Step 4:
When dividing 839 by 90, we get 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtract 810 from 839 to get 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 90

Step 5:
The number 90 fits into 295 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 893.0
If we take 270 away from 295, we end up with 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 90

Let's proceed to step 6:
When dividing 252 by 90, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 8932.0
If we subtract 180 from 252, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
90 can be fit into 720 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8932.8
Subtract 720 from 720 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
90 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 8932.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 90, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8932.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 8932.8 and a remainder of 0.0.
