Let's divide 457076 by 90
Let's see how many times 90 fits into 457076.

On to step 1:
90 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 90

Going ahead to step 2:
45 divided by 90 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 90

Advancing to step 3:
90 goes into 457 5 times with a remainder of 7.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 450 from 457 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 90

Going ahead to step 4:
70 divided by 90 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (7) from the dividend after 70, then repeat: 707 / 90

On to step 5:
90 can be fit into 707 7 times, resulting in a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 507.0
Subtract 630 from 707 to get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 90

Going ahead to step 6:
90 can be fit into 776 8 times, resulting in a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 5078.0
If we take 720 away from 776, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
90 can be fit into 560 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 5078.6
Subtracting 540 from 560 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
90 goes into 200 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 5078.62
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
90 goes into 200 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 5078.622
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 5078.622 with a remainder of 0.002.
