We divide 220815 by 90
Our goal is to divide 220815 by 90.

Moving on to step 1:
2 divided by 90 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 90

Advancing to step 2:
The number 90 fits into 22 0 times, leaving a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 90

On to step 3:
90 can be fit into 220 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 180 away from 220, we end up with 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 90

Going ahead to step 4:
When dividing 408 by 90, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 360 from 408, we get 48.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 90

Moving on to step 5:
When dividing 481 by 90, we get 5 with a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
Deduct 450 from 481 and we're left with 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 90

Step 6:
315 divided by 90 is 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 2453.0
Subtract 270 from 315 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
When dividing 450 by 90, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2453.5
The remainder is 0 after subtracting 450 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2453.5
Subtract 0 from 0 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.

Going ahead to step 9:
If we divide 0 by 90, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2453.5
Subtract 0 from 0 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.

The final outcome is 2453.5, with a leftover of 0.0.
