We divide 4585 by 90
Let's see how many times 90 fits into 4585.

Moving on to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 90

Step 2:
90 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 90

Step 3:
When dividing 458 by 90, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 450 from 458 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 90

Step 4:
When dividing 85 by 90, we get 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 85, we end up 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.

Going ahead to step 5:
90 can be fit into 850 9 times, resulting in a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 50.9
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.

Going ahead to step 6:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 50.94
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.

On to step 7:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 50.944
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.

After the division, we end up with 50.944 and a remainder of 0.004.
