We divide 90221 by 45
We want to divide 90221 by 45.

Going ahead to step 1:
45 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 45

Going ahead to step 2:
If we divide 90 by 45, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 90 from 90 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 45

Advancing to step 3:
2 divided by 45 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 2, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 45

Advancing to step 4:
22 divided by 45 is 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
The remainder is 22 after subtracting 0 from 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 45

Step 5:
45 goes into 221 4 times with a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 2004.0
If we take 180 away from 221, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 6:
410 divided by 45 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 2004.9
The remainder is 5 after subtracting 405 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
When dividing 50 by 45, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 2004.91
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 2004.911
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 2004.911 with a balance of 0.0005.
