40742404 ÷ 198 
The aim is to understand the frequency of 198 in 40742404.

Let's proceed to step 1:
If we divide 4 by 198, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 198

Let's proceed to step 2:
When dividing 40 by 198, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 198

Step 3:
When dividing 407 by 198, we get 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 396 from 407 to get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 198

Advancing to step 4:
The number 198 fits into 114 0 times, leaving a remainder of 114.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 114, we end up with 114.
Fetch the next digit (2) from the dividend, attach it to 114 and continue: 1142 / 198

On to step 5:
1142 divided by 198 is 5 with a remainder of 152.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
If we take 990 away from 1142, we end up with 152.
Take the next digit (4) from the dividend and append it to 152, then repeat: 1524 / 198

Let's proceed to step 6:
198 goes into 1524 7 times with a remainder of 138.
Record the quotient 7 as the next digit in the result. 
Result so far: 2057.0
Subtract 1386 from 1524 to get 138.
Grab the next digit (0) from the dividend, add it to 138, then carry on: 1380 / 198

Step 7:
1380 divided by 198 is 6 with a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 20576.0
The remainder is 192 after subtracting 1188 from 1380.
Grab the next digit (4) from the dividend, add it to 192, then carry on: 1924 / 198

Let's proceed to step 8:
198 goes into 1924 9 times with a remainder of 142.
Write down 9 as next digit of the result. 
Result so far: 205769.0
Subtract 1782 from 1924 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 9:
198 can be fit into 1420 7 times, resulting in a remainder of 34.
The next digit of our result is 7. 
Result so far: 205769.7
Deduct 1386 from 1420 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
The number 198 fits into 340 1 times, leaving a remainder of 142.
Record the quotient 1 as the next digit in the result. 
Result so far: 205769.71
If we take 198 away from 340, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 11:
When dividing 1420 by 198, we get 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 205769.717
If we subtract 1386 from 1420, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
198 goes into 340 1 times with a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 205769.7171
Subtracting 198 from 340 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 13:
1420 divided by 198 is 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 205769.71717
If we subtract 1386 from 1420, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
When dividing 340 by 198, we get 1 with a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 205769.717171
The remainder is 142 after subtracting 198 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 15:
1420 divided by 198 is 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 205769.7171717
The remainder is 34 after subtracting 1386 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 16:
The number 198 fits into 340 1 times, leaving a remainder of 142.
The number 1 becomes the next digit in our result. 
Result so far: 205769.71717171
Subtracting 198 from 340 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

After the division, we end up with 205769.71717171 and a remainder of 1.42e-07.
