90508840 ÷ 200 
Let's see how many times 200 fits into 90508840.

Advancing to step 1:
When dividing 9 by 200, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 200

Advancing to step 2:
90 divided by 200 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 200

Going ahead to step 3:
The number 200 fits into 905 4 times, leaving a remainder of 105.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 800 from 905, we get 105.
Fetch the next digit (0) from the dividend, attach it to 105 and continue: 1050 / 200

Moving on to step 4:
The number 200 fits into 1050 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 50 after subtracting 1000 from 1050.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 200

Let's proceed to step 5:
508 divided by 200 is 2 with a remainder of 108.
Write down 2 as next digit of the result. 
Result so far: 452.0
If we subtract 400 from 508, we get 108.
Append the next digit (8) from the dividend to 108 and continue with: 1088 / 200

On to step 6:
When dividing 1088 by 200, we get 5 with a remainder of 88.
Write down 5 as next digit of the result. 
Result so far: 4525.0
If we take 1000 away from 1088, we end up with 88.
Bring next digit (4) of the dividend behind the 88 and repeat the process: 884 / 200

Step 7:
200 can be fit into 884 4 times, resulting in a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 45254.0
If we subtract 800 from 884, we get 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 200

Going ahead to step 8:
840 divided by 200 is 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 452544.0
If we subtract 800 from 840, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
400 divided by 200 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 452544.2
If we take 400 away from 400, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
200 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 452544.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
200 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 452544.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 452544.2 with a balance of 0.0.
