We're dividing 52405 by 90 
We want to divide 52405 by 90.

On to step 1:
The number 90 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 90

Step 2:
52 divided by 90 is 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (4) from the dividend, attach it to 52 and continue: 524 / 90

Advancing to step 3:
524 divided by 90 is 5 with a remainder of 74.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 450 from 524 to get 74.
Bring next digit (0) of the dividend behind the 74 and repeat the process: 740 / 90

Advancing to step 4:
740 divided by 90 is 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
If we subtract 720 from 740, we get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 90

On to step 5:
205 divided by 90 is 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 582.0
The remainder is 25 after subtracting 180 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 6:
The number 90 fits into 250 2 times, leaving a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 582.2
Subtracting 180 from 250 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 7:
700 divided by 90 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 582.27
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 582.277
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 582.277 with a remainder of 0.007.
