We're dividing 220223 by 90 
We want to figure out the number of times 220223 can be divided by 90.

Moving on to step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 90

Advancing to step 2:
When dividing 22 by 90, we get 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 90

Step 3:
90 can be fit into 220 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 180 from 220 and we're left with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 90

Let's proceed to step 4:
90 can be fit into 402 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 360 from 402 and we're left with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 90

Moving on to step 5:
If we divide 422 by 90, we get 4 and a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 244.0
Subtracting 360 from 422 leaves us with 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 90

On to step 6:
623 divided by 90 is 6 with a remainder of 83.
The next digit of our result is 6. 
Result so far: 2446.0
Subtract 540 from 623 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 7:
The number 90 fits into 830 9 times, leaving a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 2446.9
Subtract 810 from 830 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 90, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2446.92
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2446.922
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 2446.922, with a leftover of 0.002.
