Let's divide 1661574 by 199
The aim is to understand the frequency of 199 in 1661574.

Moving on to step 1:
199 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 199

Let's proceed to step 2:
199 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 199

Moving on to step 3:
199 can be fit into 166 0 times, resulting in a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 166 to get 166.
Bring next digit (1) of the dividend behind the 166 and repeat the process: 1661 / 199

Moving on to step 4:
If we divide 1661 by 199, we get 8 and a remainder of 69.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 1592 from 1661 leaves us with 69.
Bring next digit (5) of the dividend behind the 69 and repeat the process: 695 / 199

Moving on to step 5:
199 goes into 695 3 times with a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
If we subtract 597 from 695, we get 98.
Include the next digit (7) from the dividend after 98, then repeat: 987 / 199

Going ahead to step 6:
When dividing 987 by 199, we get 4 with a remainder of 191.
Write down 4 as next digit of the result. 
Result so far: 834.0
Subtracting 796 from 987 leaves us with 191.
Fetch the next digit (4) from the dividend, attach it to 191 and continue: 1914 / 199

Let's proceed to step 7:
When dividing 1914 by 199, we get 9 with a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 8349.0
If we subtract 1791 from 1914, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 8:
When dividing 1230 by 199, we get 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 8349.6
Subtract 1194 from 1230 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
When dividing 360 by 199, we get 1 with a remainder of 161.
The number 1 becomes the next digit in our result. 
Result so far: 8349.61
Deduct 199 from 360 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 10:
199 can be fit into 1610 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 8349.618
Deduct 1592 from 1610 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
180 divided by 199 is 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 8349.618
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
The number 199 fits into 1800 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 8349.61809
Deduct 1791 from 1800 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
The number 199 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 8349.61809
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 14:
If we divide 900 by 199, we get 4 and a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 8349.6180904
If we subtract 796 from 900, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 15:
If we divide 1040 by 199, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 8349.61809045
Deduct 995 from 1040 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 8349.61809045 with a remaining 4.5e-08.
