Let's divide 539849 by 90
Our goal is to divide 539849 by 90.

Moving on to step 1:
The number 90 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 90

Step 2:
53 divided by 90 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 90

Going ahead to step 3:
90 goes into 539 5 times with a remainder of 89.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 450 from 539, we get 89.
Fetch the next digit (8) from the dividend, attach it to 89 and continue: 898 / 90

Let's proceed to step 4:
90 goes into 898 9 times with a remainder of 88.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Subtract 810 from 898 to get 88.
Include the next digit (4) from the dividend after 88, then repeat: 884 / 90

Moving on to step 5:
When dividing 884 by 90, we get 9 with a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 599.0
Deduct 810 from 884 and we're left with 74.
Take the next digit (9) from the dividend and append it to 74, then repeat: 749 / 90

Step 6:
When dividing 749 by 90, we get 8 with a remainder of 29.
The next digit of our result is 8. 
Result so far: 5998.0
Deduct 720 from 749 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
The number 90 fits into 290 3 times, leaving a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 5998.3
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 8:
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: 5998.32
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.

Let's proceed to step 9:
200 divided by 90 is 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 5998.322
If we subtract 180 from 200, we 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.

The final outcome is 5998.322, with a leftover of 0.002.
