We're dividing 456025 by 90 
We want to figure out the number of times 456025 can be divided by 90.

Advancing to step 1:
90 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 90

Step 2:
If we divide 45 by 90, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 90

Step 3:
When dividing 456 by 90, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 450 from 456 to get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 90

Advancing to step 4:
If we divide 60 by 90, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Deduct 0 from 60 and we're left with 60.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 90

Step 5:
90 goes into 602 6 times with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 506.0
The remainder is 62 after subtracting 540 from 602.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 90

Moving on to step 6:
When dividing 625 by 90, we get 6 with a remainder of 85.
Put 6 as the next digit of the answer. 
Result so far: 5066.0
Deduct 540 from 625 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 7:
When dividing 850 by 90, we get 9 with a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 5066.9
Subtracting 810 from 850 leaves us 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:
400 divided by 90 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 5066.94
Subtract 360 from 400 to 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:
The number 90 fits into 400 4 times, leaving a remainder of 40.
The next digit of our result is 4. 
Result so far: 5066.944
The remainder is 40 after subtracting 360 from 400.
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 outcome is 5066.944, with a leftover of 0.004.
