We divide 636297 by 90
We want to divide 636297 by 90.

Let's proceed to step 1:
6 divided by 90 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 90

Moving on to step 2:
90 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 90

Advancing to step 3:
The number 90 fits into 636 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 630 from 636 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 90

Moving on to step 4:
90 goes into 62 0 times with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 70.0
The remainder is 62 after subtracting 0 from 62.
Include the next digit (9) from the dividend after 62, then repeat: 629 / 90

On to step 5:
90 goes into 629 6 times with a remainder of 89.
Write down 6 as next digit of the result. 
Result so far: 706.0
Deduct 540 from 629 and we're left with 89.
Fetch the next digit (7) from the dividend, attach it to 89 and continue: 897 / 90

Let's proceed to step 6:
897 divided by 90 is 9 with a remainder of 87.
The next digit of our result is 9. 
Result so far: 7069.0
Subtracting 810 from 897 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 7:
The number 90 fits into 870 9 times, leaving a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 7069.9
Subtract 810 from 870 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 7069.96
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
If we divide 600 by 90, we get 6 and a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 7069.966
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 7069.966 with a remainder of 0.006.
