We divide 507200 by 90
We're looking to find how many times 90 goes into 507200.

Moving on to step 1:
90 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 90

Moving on to step 2:
If we divide 50 by 90, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 90

On to step 3:
If we divide 507 by 90, we get 5 and a remainder of 57.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 450 from 507 leaves us with 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 90

Step 4:
90 goes into 572 6 times with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 56.0
If we take 540 away from 572, we end up with 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 90

Step 5:
When dividing 320 by 90, we get 3 with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 563.0
If we take 270 away from 320, we end up with 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 90

Going ahead to step 6:
90 goes into 500 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5635.0
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.

Let's proceed to step 7:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5635.5
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.

Step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5635.55
If we subtract 450 from 500, we 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 5635.55 and a remainder of 0.05.
