We look at the division of 74619778 by 198 
The aim is to understand the frequency of 198 in 74619778.

On to step 1:
The number 198 fits into 7 0 times, leaving 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.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 198

Moving on to step 2:
If we divide 74 by 198, we get 0 and a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Include the next digit (6) from the dividend after 74, then repeat: 746 / 198

On to step 3:
When dividing 746 by 198, we get 3 with a remainder of 152.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 594 from 746 to get 152.
Take the next digit (1) from the dividend and append it to 152, then repeat: 1521 / 198

Let's proceed to step 4:
1521 divided by 198 is 7 with a remainder of 135.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we subtract 1386 from 1521, we get 135.
Append the next digit (9) from the dividend to 135 and continue with: 1359 / 198

Step 5:
198 can be fit into 1359 6 times, resulting in a remainder of 171.
Write down 6 as next digit of the result. 
Result so far: 376.0
The remainder is 171 after subtracting 1188 from 1359.
Append the next digit (7) from the dividend to 171 and continue with: 1717 / 198

Moving on to step 6:
198 goes into 1717 8 times with a remainder of 133.
The number 8 becomes the next digit in our result. 
Result so far: 3768.0
Subtract 1584 from 1717 to get 133.
Grab the next digit (7) from the dividend, add it to 133, then carry on: 1337 / 198

Step 7:
198 can be fit into 1337 6 times, resulting in a remainder of 149.
Put 6 as the next digit of the answer. 
Result so far: 37686.0
If we take 1188 away from 1337, we end up with 149.
Include the next digit (8) from the dividend after 149, then repeat: 1498 / 198

On to step 8:
198 can be fit into 1498 7 times, resulting in a remainder of 112.
Record the quotient 7 as the next digit in the result. 
Result so far: 376867.0
The remainder is 112 after subtracting 1386 from 1498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 9:
The number 198 fits into 1120 5 times, leaving a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 376867.5
If we subtract 990 from 1120, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
198 can be fit into 1300 6 times, resulting in a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 376867.56
Deduct 1188 from 1300 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 11:
198 goes into 1120 5 times with a remainder of 130.
The next digit of our result is 5. 
Result so far: 376867.565
Deduct 990 from 1120 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 12:
198 goes into 1300 6 times with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 376867.5656
Deduct 1188 from 1300 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 13:
If we divide 1120 by 198, we get 5 and a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 376867.56565
The remainder is 130 after subtracting 990 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 14:
The number 198 fits into 1300 6 times, leaving a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 376867.565656
Subtracting 1188 from 1300 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 15:
1120 divided by 198 is 5 with a remainder of 130.
The next digit of our result is 5. 
Result so far: 376867.5656565
The remainder is 130 after subtracting 990 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 16:
If we divide 1300 by 198, we get 6 and a remainder of 112.
The next digit of our result is 6. 
Result so far: 376867.56565656
If we take 1188 away from 1300, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The quotient of the division is 376867.56565656, and the remainder is 1.12e-07.
