We're dividing 543323 by 90 
We want to figure out the number of times 543323 can be divided by 90.

On to step 1:
If we divide 5 by 90, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 90

Step 2:
The number 90 fits into 54 0 times, leaving a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 90

Going ahead to step 3:
90 can be fit into 543 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 3 after subtracting 540 from 543.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 90

Moving on to step 4:
The number 90 fits into 33 0 times, leaving a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 60.0
Deduct 0 from 33 and we're left with 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 90

Step 5:
332 divided by 90 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 603.0
Subtract 270 from 332 to get 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 90

Let's proceed to step 6:
90 goes into 623 6 times with a remainder of 83.
Write down 6 as next digit of the result. 
Result so far: 6036.0
Subtract 540 from 623 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 7:
The number 90 fits into 830 9 times, leaving a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 6036.9
Subtract 810 from 830 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.

Step 8:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 6036.92
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 9:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 6036.922
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.

The final result is 6036.922 with a remainder of 0.002.
