We're dividing 72403852 by 199 
The aim is to understand the frequency of 199 in 72403852.

On to step 1:
7 divided by 199 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 199

Let's proceed to step 2:
The number 199 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (4) of the dividend behind the 72 and repeat the process: 724 / 199

On to step 3:
199 goes into 724 3 times with a remainder of 127.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 597 from 724, we get 127.
Grab the next digit (0) from the dividend, add it to 127, then carry on: 1270 / 199

Step 4:
When dividing 1270 by 199, we get 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtract 1194 from 1270 to get 76.
Append the next digit (3) from the dividend to 76 and continue with: 763 / 199

Moving on to step 5:
763 divided by 199 is 3 with a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 363.0
Subtracting 597 from 763 leaves us with 166.
Include the next digit (8) from the dividend after 166, then repeat: 1668 / 199

Going ahead to step 6:
When dividing 1668 by 199, we get 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 3638.0
Deduct 1592 from 1668 and we're left with 76.
Grab the next digit (5) from the dividend, add it to 76, then carry on: 765 / 199

On to step 7:
765 divided by 199 is 3 with a remainder of 168.
Record the quotient 3 as the next digit in the result. 
Result so far: 36383.0
Subtract 597 from 765 to get 168.
Take the next digit (2) from the dividend and append it to 168, then repeat: 1682 / 199

Let's proceed to step 8:
199 goes into 1682 8 times with a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 363838.0
Subtract 1592 from 1682 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 9:
When dividing 900 by 199, we get 4 with a remainder of 104.
The next digit of our result is 4. 
Result so far: 363838.4
Subtract 796 from 900 to 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.

Step 10:
The number 199 fits into 1040 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 363838.45
Subtract 995 from 1040 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
The number 199 fits into 450 2 times, leaving a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 363838.452
If we take 398 away from 450, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
If we divide 520 by 199, we get 2 and a remainder of 122.
Record the quotient 2 as the next digit in the result. 
Result so far: 363838.4522
Deduct 398 from 520 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The quotient of the division is 363838.4522, and the remainder is 0.00122.
