We're dividing 574456 by 90 
We want to divide 574456 by 90.

Step 1:
90 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 90

On to step 2:
If we divide 57 by 90, we get 0 and a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 90

Step 3:
The number 90 fits into 574 6 times, leaving a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 540 from 574, we get 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 90

On to step 4:
90 goes into 344 3 times with a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 63.0
The remainder is 74 after subtracting 270 from 344.
Append the next digit (5) from the dividend to 74 and continue with: 745 / 90

Step 5:
90 can be fit into 745 8 times, resulting in a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 638.0
Subtract 720 from 745 to get 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 90

Let's proceed to step 6:
90 can be fit into 256 2 times, resulting in a remainder of 76.
The next digit of our result is 2. 
Result so far: 6382.0
If we subtract 180 from 256, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 7:
If we divide 760 by 90, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 6382.8
Deduct 720 from 760 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 6382.84
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 90, we get 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 6382.844
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 6382.844 with a remainder of 0.004.
