We're dividing 74353686 by 198 
The aim is to understand the frequency of 198 in 74353686.

On to step 1:
198 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 198

On to step 2:
The number 198 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 198

Step 3:
If we divide 743 by 198, we get 3 and a remainder of 149.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 149 after subtracting 594 from 743.
Include the next digit (5) from the dividend after 149, then repeat: 1495 / 198

Going ahead to step 4:
The number 198 fits into 1495 7 times, leaving a remainder of 109.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 1386 from 1495 to get 109.
Bring next digit (3) of the dividend behind the 109 and repeat the process: 1093 / 198

Moving on to step 5:
When dividing 1093 by 198, we get 5 with a remainder of 103.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
Subtracting 990 from 1093 leaves us with 103.
Grab the next digit (6) from the dividend, add it to 103, then carry on: 1036 / 198

Advancing to step 6:
198 goes into 1036 5 times with a remainder of 46.
The next digit of our result is 5. 
Result so far: 3755.0
If we take 990 away from 1036, we end up with 46.
Bring next digit (8) of the dividend behind the 46 and repeat the process: 468 / 198

Let's proceed to step 7:
When dividing 468 by 198, we get 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 37552.0
If we subtract 396 from 468, we get 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 198

Advancing to step 8:
When dividing 726 by 198, we get 3 with a remainder of 132.
Use 3 as the next digit of our solution. 
Result so far: 375523.0
If we subtract 594 from 726, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 9:
1320 divided by 198 is 6 with a remainder of 132.
Write down 6 as next digit of the result. 
Result so far: 375523.6
Deduct 1188 from 1320 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 10:
When dividing 1320 by 198, we get 6 with a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 375523.66
Subtracting 1188 from 1320 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Our division results in 375523.66 with a remaining 0.132.
