7149551 divided by 199 
The aim is to understand the frequency of 199 in 7149551.

On to step 1:
When dividing 7 by 199, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 199

Advancing to step 2:
When dividing 71 by 199, we get 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 199

Moving on to step 3:
714 divided by 199 is 3 with a remainder of 117.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 597 from 714 to get 117.
Include the next digit (9) from the dividend after 117, then repeat: 1179 / 199

Advancing to step 4:
When dividing 1179 by 199, we get 5 with a remainder of 184.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 995 away from 1179, we end up with 184.
Include the next digit (5) from the dividend after 184, then repeat: 1845 / 199

Step 5:
199 can be fit into 1845 9 times, resulting in a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 359.0
Subtract 1791 from 1845 to get 54.
Append the next digit (5) from the dividend to 54 and continue with: 545 / 199

Let's proceed to step 6:
199 can be fit into 545 2 times, resulting in a remainder of 147.
The next digit of our result is 2. 
Result so far: 3592.0
The remainder is 147 after subtracting 398 from 545.
Append the next digit (1) from the dividend to 147 and continue with: 1471 / 199

Moving on to step 7:
199 goes into 1471 7 times with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 35927.0
Subtract 1393 from 1471 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 8:
The number 199 fits into 780 3 times, leaving a remainder of 183.
The number 3 becomes the next digit in our result. 
Result so far: 35927.3
If we subtract 597 from 780, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 9:
The number 199 fits into 1830 9 times, leaving a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 35927.39
Deduct 1791 from 1830 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
199 goes into 390 1 times with a remainder of 191.
The next digit of our result is 1. 
Result so far: 35927.391
Subtract 199 from 390 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 11:
If we divide 1910 by 199, we get 9 and a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 35927.3919
If we take 1791 away from 1910, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 12:
If we divide 1190 by 199, we get 5 and a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 35927.39195
If we take 995 away from 1190, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 13:
If we divide 1950 by 199, we get 9 and a remainder of 159.
The next digit of our result is 9. 
Result so far: 35927.391959
Deduct 1791 from 1950 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 14:
199 goes into 1590 7 times with a remainder of 197.
Put 7 as the next digit of the answer. 
Result so far: 35927.3919597
If we subtract 1393 from 1590, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 15:
If we divide 1970 by 199, we get 9 and a remainder of 179.
Put 9 as the next digit of the answer. 
Result so far: 35927.39195979
The remainder is 179 after subtracting 1791 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

In conclusion, the division gives 35927.39195979 with a balance of 1.79e-07.
