Let's divide 574453 by 90
Our goal is to divide 574453 by 90.

On to step 1:
If we divide 5 by 90, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 90

Going ahead to step 2:
The number 90 fits into 57 0 times, leaving a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 90

Moving on to step 3:
90 can be fit into 574 6 times, resulting in a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 540 from 574 and we're left with 34.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 90

Advancing 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

Let's proceed to step 5:
90 can be fit into 745 8 times, resulting in a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 638.0
Deduct 720 from 745 and we're left with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 90

Moving on to step 6:
90 can be fit into 253 2 times, resulting in a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 6382.0
Subtracting 180 from 253 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
When dividing 730 by 90, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 6382.8
Subtract 720 from 730 to 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.

Step 8:
90 goes into 100 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 6382.81
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 90, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 6382.811
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.

Our division results in 6382.811 with a remaining 0.001.
