We divide 570903 by 90
We're looking to find how many times 90 goes into 570903.

Advancing to step 1:
90 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 90

On to step 2:
57 divided by 90 is 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 90

Advancing to step 3:
If we divide 570 by 90, we get 6 and a remainder of 30.
The next digit of our result is 6. 
Result so far: 6.0
If we take 540 away from 570, we end up with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 90

Let's proceed to step 4:
90 can be fit into 309 3 times, resulting in a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 270 from 309 to get 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 90

Going ahead to step 5:
90 goes into 390 4 times with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 634.0
Deduct 360 from 390 and we're left with 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 90

Step 6:
When dividing 303 by 90, we get 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 6343.0
Subtract 270 from 303 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
When dividing 330 by 90, we get 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 6343.3
If we subtract 270 from 330, 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.

Moving on to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 6343.36
If we take 540 away from 600, 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.

Let's proceed to step 9:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 6343.366
Subtract 540 from 600 to 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.

The final result is 6343.366 with a remainder of 0.006.
