We divide 515994 by 90
We want to divide 515994 by 90.

Let's proceed to step 1:
When dividing 5 by 90, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 90

On to 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
If we take 0 away from 51, we end up with 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 90

Advancing to step 3:
90 can be fit into 515 5 times, resulting in a remainder of 65.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 65 after subtracting 450 from 515.
Grab the next digit (9) from the dividend, add it to 65, then carry on: 659 / 90

Advancing to step 4:
If we divide 659 by 90, we get 7 and a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtracting 630 from 659 leaves us with 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 90

Let's proceed to step 5:
299 divided by 90 is 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 573.0
Subtracting 270 from 299 leaves us with 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 90

Moving on to step 6:
If we divide 294 by 90, we get 3 and a remainder of 24.
The next digit of our result is 3. 
Result so far: 5733.0
Deduct 270 from 294 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
90 can be fit into 240 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 5733.2
If we take 180 away from 240, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
90 can be fit into 600 6 times, resulting in a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 5733.26
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.

Going ahead to step 9:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 5733.266
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 5733.266, and the remainder is 0.006.
