Let's divide 9543539 by 90
Our goal is to divide 9543539 by 90.

Moving on to step 1:
90 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 90

Going ahead to step 2:
When dividing 95 by 90, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 90 from 95, we get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 90

Step 3:
90 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 54, we end up with 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 90

Advancing to step 4:
If we divide 543 by 90, we get 6 and a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we subtract 540 from 543, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 90

Going ahead to step 5:
The number 90 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 1060.0
Subtract 0 from 35 to get 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 90

Let's proceed to step 6:
353 divided by 90 is 3 with a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 10603.0
If we take 270 away from 353, we end up with 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 90

Advancing to step 7:
90 can be fit into 839 9 times, resulting in a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 106039.0
The remainder is 29 after subtracting 810 from 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
When dividing 290 by 90, we get 3 with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 106039.3
Deduct 270 from 290 and we're left 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.

Step 9:
When dividing 200 by 90, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 106039.32
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 10:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 106039.322
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.

After the division, we end up with 106039.322 and a remainder of 0.002.
