We're dividing 12615081 by 198 
The aim is to understand the frequency of 198 in 12615081.

Moving on to step 1:
The number 198 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 198

On to step 2:
198 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 198

Step 3:
198 goes into 126 0 times with a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 126 after subtracting 0 from 126.
Fetch the next digit (1) from the dividend, attach it to 126 and continue: 1261 / 198

Advancing to step 4:
If we divide 1261 by 198, we get 6 and a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 1188 from 1261 to get 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 198

Moving on to step 5:
198 goes into 735 3 times with a remainder of 141.
The next digit of our result is 3. 
Result so far: 63.0
Subtract 594 from 735 to get 141.
Bring next digit (0) of the dividend behind the 141 and repeat the process: 1410 / 198

Advancing to step 6:
When dividing 1410 by 198, we get 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 637.0
The remainder is 24 after subtracting 1386 from 1410.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 198

Let's proceed to step 7:
248 divided by 198 is 1 with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 6371.0
If we take 198 away from 248, we end up with 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 198

Step 8:
If we divide 501 by 198, we get 2 and a remainder of 105.
Put 2 as the next digit of the answer. 
Result so far: 63712.0
Subtracting 396 from 501 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 9:
The number 198 fits into 1050 5 times, leaving a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 63712.5
Subtract 990 from 1050 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
198 goes into 600 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 63712.53
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
The number 198 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 63712.53
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
198 goes into 600 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 63712.5303
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
If we divide 60 by 198, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 63712.5303
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
When dividing 600 by 198, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 63712.530303
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 15:
When dividing 60 by 198, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 63712.530303
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 16:
If we divide 600 by 198, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 63712.53030303
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 63712.53030303 with a balance of 6e-09.
