We look at the division of 902133 by 90 
We're looking to find how many times 90 goes into 902133.

Let's proceed to step 1:
The number 90 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 90

Moving on to step 2:
90 can be fit into 90 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 90 from 90.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 90

Advancing to step 3:
If we divide 2 by 90, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 90

Going ahead to step 4:
If we divide 21 by 90, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 100.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 90

Let's proceed to step 5:
If we divide 213 by 90, we get 2 and a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 1002.0
The remainder is 33 after subtracting 180 from 213.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 90

Step 6:
333 divided by 90 is 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 10023.0
Deduct 270 from 333 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 7:
When dividing 630 by 90, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 10023.7
Subtracting 630 from 630 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 90, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10023.7
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10023.7
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 10023.7 with a balance of 0.0.
