We're dividing 223405 by 90 
Let's see how many times 90 fits into 223405.

Step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 90

On to step 2:
When dividing 22 by 90, we get 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 90

Advancing to step 3:
The number 90 fits into 223 2 times, leaving a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 180 from 223 and we're left with 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 90

Let's proceed to step 4:
When dividing 434 by 90, we get 4 with a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 360 from 434 and we're left with 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 90

Advancing to step 5:
90 can be fit into 740 8 times, resulting in a remainder of 20.
The next digit of our result is 8. 
Result so far: 248.0
If we take 720 away from 740, we end up with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 90

Step 6:
90 goes into 205 2 times with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 2482.0
If we take 180 away from 205, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
If we divide 250 by 90, we get 2 and a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 2482.2
Subtracting 180 from 250 leaves us 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.

Advancing to step 8:
The number 90 fits into 700 7 times, leaving a remainder of 70.
The next digit of our result is 7. 
Result so far: 2482.27
If we subtract 630 from 700, we get 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 9:
The number 90 fits into 700 7 times, leaving a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 2482.277
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.

The final outcome is 2482.277, with a leftover of 0.007.
