We look at the division of 487636 by 90 
We want to divide 487636 by 90.

On to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 90

Moving on to step 2:
90 can be fit into 48 0 times, resulting in a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 90

Going ahead to step 3:
90 goes into 487 5 times with a remainder of 37.
The next digit of our result is 5. 
Result so far: 5.0
If we take 450 away from 487, we end up with 37.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 90

Step 4:
When dividing 376 by 90, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 54.0
The remainder is 16 after subtracting 360 from 376.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 90

Advancing to step 5:
The number 90 fits into 163 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 541.0
The remainder is 73 after subtracting 90 from 163.
Include the next digit (6) from the dividend after 73, then repeat: 736 / 90

Step 6:
90 can be fit into 736 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 5418.0
Subtract 720 from 736 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
160 divided by 90 is 1 with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 5418.1
Subtracting 90 from 160 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.

On to step 8:
If we divide 700 by 90, we get 7 and a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 5418.17
Subtracting 630 from 700 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.

Going ahead to step 9:
90 goes into 700 7 times with a remainder of 70.
The next digit of our result is 7. 
Result so far: 5418.177
If we take 630 away from 700, we end up 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.

The final result is 5418.177 with a remainder of 0.007.
