We divide 542539 by 90
We want to divide 542539 by 90.

Advancing to step 1:
When dividing 5 by 90, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 90

Going ahead to step 2:
The number 90 fits into 54 0 times, leaving a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 90

Advancing to step 3:
The number 90 fits into 542 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 2 after subtracting 540 from 542.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 90

Moving on to step 4:
25 divided by 90 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 60.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 90

Advancing to step 5:
The number 90 fits into 253 2 times, leaving a remainder of 73.
The next digit of our result is 2. 
Result so far: 602.0
If we subtract 180 from 253, we get 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 90

On to step 6:
When dividing 739 by 90, we get 8 with a remainder of 19.
The next digit of our result is 8. 
Result so far: 6028.0
If we subtract 720 from 739, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
When dividing 190 by 90, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 6028.2
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 90 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 6028.21
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 6028.211
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 6028.211 with a remainder of 0.001.
