We're dividing 1242909 by 164 
The aim is to understand the frequency of 164 in 1242909.

On to step 1:
164 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 164

On to step 2:
12 divided by 164 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 164

Moving on to step 3:
164 goes into 124 0 times with a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Include the next digit (2) from the dividend after 124, then repeat: 1242 / 164

Advancing to step 4:
164 goes into 1242 7 times with a remainder of 94.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 1148 away from 1242, we end up with 94.
Append the next digit (9) from the dividend to 94 and continue with: 949 / 164

Moving on to step 5:
949 divided by 164 is 5 with a remainder of 129.
The next digit of our result is 5. 
Result so far: 75.0
The remainder is 129 after subtracting 820 from 949.
Include the next digit (0) from the dividend after 129, then repeat: 1290 / 164

Going ahead to step 6:
If we divide 1290 by 164, we get 7 and a remainder of 142.
Put 7 as the next digit of the answer. 
Result so far: 757.0
The remainder is 142 after subtracting 1148 from 1290.
Append the next digit (9) from the dividend to 142 and continue with: 1429 / 164

Let's proceed to step 7:
When dividing 1429 by 164, we get 8 with a remainder of 117.
Use 8 as the next digit of our solution. 
Result so far: 7578.0
If we subtract 1312 from 1429, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 8:
164 goes into 1170 7 times with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 7578.7
If we take 1148 away from 1170, we end up 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.

Step 9:
The number 164 fits into 220 1 times, leaving a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 7578.71
The remainder is 56 after subtracting 164 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
560 divided by 164 is 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 7578.713
Subtract 492 from 560 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
680 divided by 164 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 7578.7134
Subtracting 656 from 680 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.

On to step 12:
The number 164 fits into 240 1 times, leaving a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 7578.71341
Deduct 164 from 240 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
760 divided by 164 is 4 with a remainder of 104.
The next digit of our result is 4. 
Result so far: 7578.713414
The remainder is 104 after subtracting 656 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 14:
When dividing 1040 by 164, we get 6 with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 7578.7134146
Subtract 984 from 1040 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 15:
The number 164 fits into 560 3 times, leaving a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 7578.71341463
If we subtract 492 from 560, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 7578.71341463 with a remainder of 6.8e-08.
