We're dividing 19239980 by 200 
We want to figure out the number of times 19239980 can be divided by 200.

On to step 1:
When dividing 1 by 200, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 200

Step 2:
200 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 200

On to step 3:
192 divided by 200 is 0 with a remainder of 192.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 192, we end up with 192.
Include the next digit (3) from the dividend after 192, then repeat: 1923 / 200

Let's proceed to step 4:
200 goes into 1923 9 times with a remainder of 123.
The next digit of our result is 9. 
Result so far: 9.0
If we take 1800 away from 1923, we end up with 123.
Bring next digit (9) of the dividend behind the 123 and repeat the process: 1239 / 200

Going ahead to step 5:
1239 divided by 200 is 6 with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Deduct 1200 from 1239 and we're left with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 200

Let's proceed to step 6:
399 divided by 200 is 1 with a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 961.0
Subtracting 200 from 399 leaves us with 199.
Take the next digit (8) from the dividend and append it to 199, then repeat: 1998 / 200

Going ahead to step 7:
1998 divided by 200 is 9 with a remainder of 198.
The next digit of our result is 9. 
Result so far: 9619.0
The remainder is 198 after subtracting 1800 from 1998.
Append the next digit (0) from the dividend to 198 and continue with: 1980 / 200

Going ahead to step 8:
The number 200 fits into 1980 9 times, leaving a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 96199.0
Subtract 1800 from 1980 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 9:
200 can be fit into 1800 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 96199.9
Subtract 1800 from 1800 to 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.

Let's proceed to step 10:
If we divide 0 by 200, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 96199.9
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.

On to step 11:
0 divided by 200 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 96199.9
Subtract 0 from 0 to 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.

Our division results in 96199.9 with a remaining 0.0.
