220310 divided by 90 
Our goal is to divide 220310 by 90.

Step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 90

Let's proceed to step 2:
If we divide 22 by 90, we get 0 and a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 90

Let's proceed to step 3:
220 divided by 90 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 180 away from 220, we end up with 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 90

Going ahead to step 4:
If we divide 403 by 90, we get 4 and a remainder of 43.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 43 after subtracting 360 from 403.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 90

On to step 5:
90 can be fit into 431 4 times, resulting in a remainder of 71.
The next digit of our result is 4. 
Result so far: 244.0
If we take 360 away from 431, we end up with 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 90

Let's proceed to step 6:
If we divide 710 by 90, we get 7 and a remainder of 80.
Record the quotient 7 as the next digit in the result. 
Result so far: 2447.0
If we subtract 630 from 710, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 7:
If we divide 800 by 90, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 2447.8
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
When dividing 800 by 90, we get 8 with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 2447.88
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 2447.88 with a remainder of 0.08.
