Let's divide 1909999 by 200
The aim is to understand the frequency of 200 in 1909999.

Going ahead to step 1:
When dividing 1 by 200, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 200

Going ahead to step 2:
19 divided by 200 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 200

On to step 3:
200 can be fit into 190 0 times, resulting in a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 190, we end up with 190.
Include the next digit (9) from the dividend after 190, then repeat: 1909 / 200

Going ahead to step 4:
If we divide 1909 by 200, we get 9 and a remainder of 109.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 1800 from 1909 to get 109.
Bring next digit (9) of the dividend behind the 109 and repeat the process: 1099 / 200

Let's proceed to step 5:
200 can be fit into 1099 5 times, resulting in a remainder of 99.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we subtract 1000 from 1099, we get 99.
Grab the next digit (9) from the dividend, add it to 99, then carry on: 999 / 200

Step 6:
200 can be fit into 999 4 times, resulting in a remainder of 199.
Put 4 as the next digit of the answer. 
Result so far: 954.0
Subtract 800 from 999 to get 199.
Fetch the next digit (9) from the dividend, attach it to 199 and continue: 1999 / 200

Moving on to step 7:
200 goes into 1999 9 times with a remainder of 199.
Put 9 as the next digit of the answer. 
Result so far: 9549.0
Subtracting 1800 from 1999 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 8:
1990 divided by 200 is 9 with a remainder of 190.
Record the quotient 9 as the next digit in the result. 
Result so far: 9549.9
If we take 1800 away from 1990, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 9:
If we divide 1900 by 200, we get 9 and a remainder of 100.
The next digit of our result is 9. 
Result so far: 9549.99
If we subtract 1800 from 1900, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 9549.99 and a remainder of 0.1.
