We're dividing 74398329 by 198 
The aim is to understand the frequency of 198 in 74398329.

Moving on to step 1:
When dividing 7 by 198, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 198

Let's proceed to step 2:
198 goes into 74 0 times with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 198

Step 3:
743 divided by 198 is 3 with a remainder of 149.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 149 after subtracting 594 from 743.
Take the next digit (9) from the dividend and append it to 149, then repeat: 1499 / 198

On to step 4:
198 can be fit into 1499 7 times, resulting in a remainder of 113.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 1386 from 1499, we get 113.
Bring next digit (8) of the dividend behind the 113 and repeat the process: 1138 / 198

Advancing to step 5:
198 goes into 1138 5 times with a remainder of 148.
The number 5 becomes the next digit in our result. 
Result so far: 375.0
Subtract 990 from 1138 to get 148.
Bring next digit (3) of the dividend behind the 148 and repeat the process: 1483 / 198

Moving on to step 6:
198 can be fit into 1483 7 times, resulting in a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 3757.0
The remainder is 97 after subtracting 1386 from 1483.
Bring next digit (2) of the dividend behind the 97 and repeat the process: 972 / 198

Let's proceed to step 7:
The number 198 fits into 972 4 times, leaving a remainder of 180.
The number 4 becomes the next digit in our result. 
Result so far: 37574.0
The remainder is 180 after subtracting 792 from 972.
Fetch the next digit (9) from the dividend, attach it to 180 and continue: 1809 / 198

Moving on to step 8:
198 goes into 1809 9 times with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 375749.0
Deduct 1782 from 1809 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
When dividing 270 by 198, we get 1 with a remainder of 72.
The next digit of our result is 1. 
Result so far: 375749.1
If we take 198 away from 270, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
198 goes into 720 3 times with a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 375749.13
If we take 594 away from 720, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 11:
When dividing 1260 by 198, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 375749.136
Subtract 1188 from 1260 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
If we divide 720 by 198, we get 3 and a remainder of 126.
The next digit of our result is 3. 
Result so far: 375749.1363
Deduct 594 from 720 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 13:
The number 198 fits into 1260 6 times, leaving a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 375749.13636
If we subtract 1188 from 1260, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
198 can be fit into 720 3 times, resulting in a remainder of 126.
Record the quotient 3 as the next digit in the result. 
Result so far: 375749.136363
The remainder is 126 after subtracting 594 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 15:
If we divide 1260 by 198, we get 6 and a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 375749.1363636
Subtracting 1188 from 1260 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 16:
198 goes into 720 3 times with a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 375749.13636363
Subtract 594 from 720 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The quotient of the division is 375749.13636363, and the remainder is 1.26e-07.
