539804 ÷ 90 
Let's see how many times 90 fits into 539804.

Going ahead to step 1:
90 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 90

Step 2:
When dividing 53 by 90, we get 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 90

Advancing to step 3:
90 goes into 539 5 times with a remainder of 89.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 450 from 539 leaves us with 89.
Take the next digit (8) from the dividend and append it to 89, then repeat: 898 / 90

Going ahead to step 4:
When dividing 898 by 90, we get 9 with a remainder of 88.
Write down 9 as next digit of the result. 
Result so far: 59.0
The remainder is 88 after subtracting 810 from 898.
Bring next digit (0) of the dividend behind the 88 and repeat the process: 880 / 90

Going ahead to step 5:
When dividing 880 by 90, we get 9 with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 599.0
Subtracting 810 from 880 leaves us with 70.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 90

On to step 6:
When dividing 704 by 90, we get 7 with a remainder of 74.
The next digit of our result is 7. 
Result so far: 5997.0
Subtracting 630 from 704 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
90 goes into 740 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 5997.8
Subtracting 720 from 740 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 8:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 5997.82
Subtract 180 from 200 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 9:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 5997.822
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.

Our division results in 5997.822 with a remaining 0.002.
