We look at the division of 77963248 by 198 
The aim is to understand the frequency of 198 in 77963248.

Going ahead to step 1:
The number 198 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 198

Going ahead to step 2:
If we divide 77 by 198, we get 0 and a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 198

Going ahead to step 3:
198 goes into 779 3 times with a remainder of 185.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 185 after subtracting 594 from 779.
Include the next digit (6) from the dividend after 185, then repeat: 1856 / 198

Let's proceed to step 4:
When dividing 1856 by 198, we get 9 with a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtracting 1782 from 1856 leaves us with 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 198

Moving on to step 5:
198 goes into 743 3 times with a remainder of 149.
Record the quotient 3 as the next digit in the result. 
Result so far: 393.0
Deduct 594 from 743 and we're left with 149.
Fetch the next digit (2) from the dividend, attach it to 149 and continue: 1492 / 198

On to step 6:
If we divide 1492 by 198, we get 7 and a remainder of 106.
Use 7 as the next digit of our solution. 
Result so far: 3937.0
Subtracting 1386 from 1492 leaves us with 106.
Take the next digit (4) from the dividend and append it to 106, then repeat: 1064 / 198

Advancing to step 7:
198 can be fit into 1064 5 times, resulting in a remainder of 74.
The number 5 becomes the next digit in our result. 
Result so far: 39375.0
Subtracting 990 from 1064 leaves us with 74.
Append the next digit (8) from the dividend to 74 and continue with: 748 / 198

Let's proceed to step 8:
198 goes into 748 3 times with a remainder of 154.
The number 3 becomes the next digit in our result. 
Result so far: 393753.0
If we take 594 away from 748, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 9:
198 can be fit into 1540 7 times, resulting in a remainder of 154.
Use 7 as the next digit of our solution. 
Result so far: 393753.7
If we take 1386 away from 1540, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 10:
If we divide 1540 by 198, we get 7 and a remainder of 154.
Put 7 as the next digit of the answer. 
Result so far: 393753.77
If we subtract 1386 from 1540, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

In conclusion, the division gives 393753.77 with a balance of 0.154.
