We're dividing 524480 by 90 
We want to figure out the number of times 524480 can be divided by 90.

Let's proceed to step 1:
If we divide 5 by 90, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 90

On to step 2:
52 divided by 90 is 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 90

On to step 3:
If we divide 524 by 90, we get 5 and a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 450 from 524, we get 74.
Grab the next digit (4) from the dividend, add it to 74, then carry on: 744 / 90

Advancing to step 4:
90 goes into 744 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 58.0
The remainder is 24 after subtracting 720 from 744.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 90

Step 5:
When dividing 248 by 90, we get 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 582.0
Subtracting 180 from 248 leaves us with 68.
Fetch the next digit (0) from the dividend, attach it to 68 and continue: 680 / 90

Moving on to step 6:
90 goes into 680 7 times with a remainder of 50.
The next digit of our result is 7. 
Result so far: 5827.0
If we take 630 away from 680, 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.

Going ahead to step 7:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5827.5
Deduct 450 from 500 and we're left 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.

On to step 8:
500 divided by 90 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5827.55
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 5827.55 and a remainder of 0.05.
