We look at the division of 12466561 by 342 
The aim is to understand the frequency of 342 in 12466561.

Step 1:
If we divide 1 by 342, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 342

Going ahead to step 2:
The number 342 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 342

Going ahead to step 3:
342 goes into 124 0 times with a remainder of 124.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 124 to get 124.
Take the next digit (6) from the dividend and append it to 124, then repeat: 1246 / 342

Moving on to step 4:
When dividing 1246 by 342, we get 3 with a remainder of 220.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1026 from 1246, we get 220.
Append the next digit (6) from the dividend to 220 and continue with: 2206 / 342

Going ahead to step 5:
When dividing 2206 by 342, we get 6 with a remainder of 154.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we subtract 2052 from 2206, we get 154.
Take the next digit (5) from the dividend and append it to 154, then repeat: 1545 / 342

Step 6:
The number 342 fits into 1545 4 times, leaving a remainder of 177.
Record the quotient 4 as the next digit in the result. 
Result so far: 364.0
The remainder is 177 after subtracting 1368 from 1545.
Include the next digit (6) from the dividend after 177, then repeat: 1776 / 342

Moving on to step 7:
If we divide 1776 by 342, we get 5 and a remainder of 66.
Use 5 as the next digit of our solution. 
Result so far: 3645.0
Deduct 1710 from 1776 and we're left with 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 342

Step 8:
If we divide 661 by 342, we get 1 and a remainder of 319.
Write down 1 as next digit of the result. 
Result so far: 36451.0
The remainder is 319 after subtracting 342 from 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Step 9:
342 can be fit into 3190 9 times, resulting in a remainder of 112.
Use 9 as the next digit of our solution. 
Result so far: 36451.9
The remainder is 112 after subtracting 3078 from 3190.
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 10:
1120 divided by 342 is 3 with a remainder of 94.
Use 3 as the next digit of our solution. 
Result so far: 36451.93
Deduct 1026 from 1120 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 11:
342 goes into 940 2 times with a remainder of 256.
Put 2 as the next digit of the answer. 
Result so far: 36451.932
The remainder is 256 after subtracting 684 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 12:
When dividing 2560 by 342, we get 7 with a remainder of 166.
Put 7 as the next digit of the answer. 
Result so far: 36451.9327
Subtract 2394 from 2560 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 13:
342 can be fit into 1660 4 times, resulting in a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 36451.93274
If we subtract 1368 from 1660, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 14:
342 goes into 2920 8 times with a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 36451.932748
If we take 2736 away from 2920, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 15:
The number 342 fits into 1840 5 times, leaving a remainder of 130.
The next digit of our result is 5. 
Result so far: 36451.9327485
Deduct 1710 from 1840 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.

On to step 16:
When dividing 1300 by 342, we get 3 with a remainder of 274.
The number 3 becomes the next digit in our result. 
Result so far: 36451.93274853
Subtracting 1026 from 1300 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

In conclusion, the division gives 36451.93274853 with a balance of 2.74e-07.
