We divide 280330 by 90
We want to divide 280330 by 90.

Advancing to step 1:
2 divided by 90 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 90

On to step 2:
28 divided by 90 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 90

Going ahead to step 3:
When dividing 280 by 90, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 270 from 280 and we're left with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 90

Step 4:
When dividing 103 by 90, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 13 after subtracting 90 from 103.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 90

Let's proceed to step 5:
If we divide 133 by 90, we get 1 and a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 311.0
If we subtract 90 from 133, we get 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 90

Advancing to step 6:
If we divide 430 by 90, we get 4 and a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 3114.0
If we take 360 away from 430, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 7:
When dividing 700 by 90, we get 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 3114.7
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
The number 90 fits into 700 7 times, leaving a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 3114.77
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 3114.77, and the remainder is 0.07.
