We look at the division of 432203 by 90 
We want to divide 432203 by 90.

Step 1:
90 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 90

Going ahead to step 2:
43 divided by 90 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 90

Advancing to step 3:
If we divide 432 by 90, we get 4 and a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 72 after subtracting 360 from 432.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 90

Moving on to step 4:
The number 90 fits into 722 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 720 from 722 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 90

Let's proceed to step 5:
When dividing 20 by 90, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 480.0
If we subtract 0 from 20, we get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 90

Advancing to step 6:
90 can be fit into 203 2 times, resulting in a remainder of 23.
The next digit of our result is 2. 
Result so far: 4802.0
If we subtract 180 from 203, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
90 can be fit into 230 2 times, resulting in a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 4802.2
If we take 180 away from 230, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 4802.25
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
500 divided by 90 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 4802.255
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 4802.255 with a remainder of 0.005.
