We look at the division of 724585 by 90 
Our goal is to divide 724585 by 90.

Moving on to step 1:
7 divided by 90 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 90

Going ahead to step 2:
90 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 90

On to step 3:
The number 90 fits into 724 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 4 after subtracting 720 from 724.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 90

Step 4:
45 divided by 90 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we subtract 0 from 45, we get 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 90

On to step 5:
The number 90 fits into 458 5 times, leaving a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 805.0
Subtract 450 from 458 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 90

Step 6:
If we divide 85 by 90, we get 0 and a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 8050.0
Subtract 0 from 85 to get 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 7:
850 divided by 90 is 9 with a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 8050.9
If we subtract 810 from 850, we 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.

Step 8:
When dividing 400 by 90, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 8050.94
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:
90 goes into 400 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 8050.944
If we take 360 away from 400, we end up 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.

Our division results in 8050.944 with a remaining 0.004.
