456908 divided by 90 
Our goal is to divide 456908 by 90.

Moving on to step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 90

Step 2:
90 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 90

Step 3:
90 can be fit into 456 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 450 from 456, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 90

Let's proceed to step 4:
69 divided by 90 is 0 with a remainder of 69.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 69, we end up with 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 90

Let's proceed to step 5:
The number 90 fits into 690 7 times, leaving a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 507.0
Subtract 630 from 690 to get 60.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 90

Step 6:
The number 90 fits into 608 6 times, leaving a remainder of 68.
The next digit of our result is 6. 
Result so far: 5076.0
Subtracting 540 from 608 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
The number 90 fits into 680 7 times, leaving a remainder of 50.
The next digit of our result is 7. 
Result so far: 5076.7
The remainder is 50 after subtracting 630 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 90 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5076.75
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
500 divided by 90 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 5076.755
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 5076.755, with a leftover of 0.005.
