Let's divide 512462 by 90
We're looking to find how many times 90 goes into 512462.

Going ahead to step 1:
90 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 90

Step 2:
51 divided by 90 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 90

Advancing to step 3:
90 goes into 512 5 times with a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 62 after subtracting 450 from 512.
Include the next digit (4) from the dividend after 62, then repeat: 624 / 90

Step 4:
The number 90 fits into 624 6 times, leaving a remainder of 84.
The next digit of our result is 6. 
Result so far: 56.0
Subtract 540 from 624 to get 84.
Take the next digit (6) from the dividend and append it to 84, then repeat: 846 / 90

Going ahead to step 5:
If we divide 846 by 90, we get 9 and a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 569.0
Deduct 810 from 846 and we're left with 36.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 90

Step 6:
If we divide 362 by 90, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 5694.0
Deduct 360 from 362 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
90 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5694.0
Deduct 0 from 20 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.

Advancing to step 8:
200 divided by 90 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 5694.02
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.

Step 9:
200 divided by 90 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 5694.022
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.

In conclusion, the division gives 5694.022 with a balance of 0.002.
