539160 ÷ 90 
We want to divide 539160 by 90.

Moving on to step 1:
90 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 90

Advancing to step 2:
90 can be fit into 53 0 times, resulting in a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 90

On to step 3:
90 goes into 539 5 times with a remainder of 89.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 450 from 539, we get 89.
Include the next digit (1) from the dividend after 89, then repeat: 891 / 90

Step 4:
If we divide 891 by 90, we get 9 and a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 59.0
If we subtract 810 from 891, we get 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 90

Moving on to step 5:
The number 90 fits into 816 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 599.0
The remainder is 6 after subtracting 810 from 816.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 90

Advancing to step 6:
When dividing 60 by 90, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 5990.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
If we divide 600 by 90, we get 6 and a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 5990.6
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
The number 90 fits into 600 6 times, leaving a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 5990.66
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 5990.66, with a leftover of 0.06.
