We look at the division of 18002 by 90 
Let's see how many times 90 fits into 18002.

Advancing to step 1:
90 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 90

Moving on to step 2:
If we divide 18 by 90, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 90

Going ahead to step 3:
90 can be fit into 180 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 180 away from 180, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 90

Advancing to step 4:
If we divide 0 by 90, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 0, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 90

Step 5:
The number 90 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 200.0
The remainder is 2 after subtracting 0 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
When dividing 20 by 90, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
If we take 0 away from 20, 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:
200 divided by 90 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 200.02
Subtracting 180 from 200 leaves us 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.

Going ahead to step 8:
90 goes into 200 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 200.022
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 quotient of the division is 200.022, and the remainder is 0.002.
