We divide 22643040 by 90
We're looking to find how many times 90 goes into 22643040.

Going ahead to step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
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

Going ahead to step 2:
90 can be fit into 22 0 times, resulting in a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 90

Moving on to step 3:
If we divide 226 by 90, we get 2 and a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 180 from 226 leaves us with 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 90

On to step 4:
90 goes into 464 5 times with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 450 from 464 and we're left with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 90

Advancing to step 5:
If we divide 143 by 90, we get 1 and a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 251.0
If we take 90 away from 143, we end up with 53.
Grab the next digit (0) from the dividend, add it to 53, then carry on: 530 / 90

On to step 6:
The number 90 fits into 530 5 times, leaving a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 2515.0
Deduct 450 from 530 and we're left with 80.
Take the next digit (4) from the dividend and append it to 80, then repeat: 804 / 90

Step 7:
The number 90 fits into 804 8 times, leaving a remainder of 84.
The next digit of our result is 8. 
Result so far: 25158.0
If we take 720 away from 804, we end up with 84.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 90

Let's proceed to step 8:
90 goes into 840 9 times with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 251589.0
Subtracting 810 from 840 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
90 can be fit into 300 3 times, resulting in a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 251589.3
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
If we divide 300 by 90, we get 3 and a remainder of 30.
The next digit of our result is 3. 
Result so far: 251589.33
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 251589.33 with a balance of 0.03.
