We look at the division of 90452 by 9 
We want to divide 90452 by 9.

Advancing to step 1:
9 can be fit into 9 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 9

Going ahead to step 2:
9 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 9

Advancing to step 3:
9 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 9

Step 4:
If we divide 45 by 9, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1005.0
The remainder is 0 after subtracting 45 from 45.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 9

Going ahead to step 5:
If we divide 2 by 9, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 10050.0
If we subtract 0 from 2, we get 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:
20 divided by 9 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 10050.2
Deduct 18 from 20 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.

Advancing to step 7:
The number 9 fits into 20 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 10050.22
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 10050.22 with a remainder of 0.002.
