We look at the division of 66497253 by 342 
The aim is to understand the frequency of 342 in 66497253.

Step 1:
6 divided by 342 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 342

Step 2:
When dividing 66 by 342, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 342

Let's proceed to step 3:
The number 342 fits into 664 1 times, leaving a remainder of 322.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 342 from 664 leaves us with 322.
Include the next digit (9) from the dividend after 322, then repeat: 3229 / 342

Step 4:
342 goes into 3229 9 times with a remainder of 151.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 3078 from 3229 and we're left with 151.
Grab the next digit (7) from the dividend, add it to 151, then carry on: 1517 / 342

Step 5:
The number 342 fits into 1517 4 times, leaving a remainder of 149.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
Deduct 1368 from 1517 and we're left with 149.
Fetch the next digit (2) from the dividend, attach it to 149 and continue: 1492 / 342

Advancing to step 6:
1492 divided by 342 is 4 with a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 1944.0
If we subtract 1368 from 1492, we get 124.
Bring next digit (5) of the dividend behind the 124 and repeat the process: 1245 / 342

Let's proceed to step 7:
The number 342 fits into 1245 3 times, leaving a remainder of 219.
The number 3 becomes the next digit in our result. 
Result so far: 19443.0
Deduct 1026 from 1245 and we're left with 219.
Grab the next digit (3) from the dividend, add it to 219, then carry on: 2193 / 342

Moving on to step 8:
2193 divided by 342 is 6 with a remainder of 141.
Use 6 as the next digit of our solution. 
Result so far: 194436.0
Subtract 2052 from 2193 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 9:
342 can be fit into 1410 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 194436.4
If we subtract 1368 from 1410, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
342 can be fit into 420 1 times, resulting in a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 194436.41
The remainder is 78 after subtracting 342 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
If we divide 780 by 342, we get 2 and a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 194436.412
If we subtract 684 from 780, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
342 can be fit into 960 2 times, resulting in a remainder of 276.
Put 2 as the next digit of the answer. 
Result so far: 194436.4122
Subtracting 684 from 960 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Our division results in 194436.4122 with a remaining 0.00276.
