We look at the division of 12392101 by 67 
The aim is to understand the frequency of 67 in 12392101.

Step 1:
67 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 67

Moving on to step 2:
67 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 67

Step 3:
67 goes into 123 1 times with a remainder of 56.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 67 from 123, we get 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 67

Going ahead to step 4:
The number 67 fits into 569 8 times, leaving a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 536 from 569 to get 33.
Append the next digit (2) from the dividend to 33 and continue with: 332 / 67

Advancing to step 5:
67 goes into 332 4 times with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 184.0
Subtracting 268 from 332 leaves us with 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 67

Step 6:
641 divided by 67 is 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 1849.0
If we subtract 603 from 641, we get 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 67

Step 7:
67 can be fit into 380 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 18495.0
Subtracting 335 from 380 leaves us with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 67

Advancing to step 8:
451 divided by 67 is 6 with a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 184956.0
Deduct 402 from 451 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
490 divided by 67 is 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 184956.7
If we take 469 away from 490, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
67 can be fit into 210 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 184956.73
The remainder is 9 after subtracting 201 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
90 divided by 67 is 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 184956.731
Subtract 67 from 90 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 12:
When dividing 230 by 67, we get 3 with a remainder of 29.
The next digit of our result is 3. 
Result so far: 184956.7313
Deduct 201 from 230 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 13:
290 divided by 67 is 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 184956.73134
Deduct 268 from 290 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
When dividing 220 by 67, we get 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 184956.731343
If we take 201 away from 220, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 15:
190 divided by 67 is 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 184956.7313432
Subtracting 134 from 190 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 16:
If we divide 560 by 67, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 184956.73134328
Subtracting 536 from 560 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 184956.73134328 with a remaining 2.4e-08.
