4502 divided by 90 
We want to divide 4502 by 90.

On to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 90

Let's proceed to step 2:
If we divide 45 by 90, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 90

Moving on to step 3:
450 divided by 90 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 450 from 450 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 90

Advancing to step 4:
2 divided by 90 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 2 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 5:
90 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 20, we 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.

On to step 6:
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: 50.02
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 7:
When dividing 200 by 90, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 50.022
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 result is 50.022 with a remainder of 0.002.
