66978323 ÷ 164 
The aim is to understand the frequency of 164 in 66978323.

Step 1:
164 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 164

Advancing to step 2:
164 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 164

Let's proceed to step 3:
164 can be fit into 669 4 times, resulting in a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 656 from 669 to get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 164

Going ahead to step 4:
When dividing 137 by 164, we get 0 with a remainder of 137.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 137, we end up with 137.
Bring next digit (8) of the dividend behind the 137 and repeat the process: 1378 / 164

Let's proceed to step 5:
The number 164 fits into 1378 8 times, leaving a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 408.0
Subtract 1312 from 1378 to get 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 164

Advancing to step 6:
When dividing 663 by 164, we get 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4084.0
Subtract 656 from 663 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 164

Moving on to step 7:
The number 164 fits into 72 0 times, leaving a remainder of 72.
The next digit of our result is 0. 
Result so far: 40840.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (3) from the dividend and append it to 72, then repeat: 723 / 164

On to step 8:
164 can be fit into 723 4 times, resulting in a remainder of 67.
Record the quotient 4 as the next digit in the result. 
Result so far: 408404.0
Subtracting 656 from 723 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
164 goes into 670 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 408404.4
Subtracting 656 from 670 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
140 divided by 164 is 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 408404.4
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
When dividing 1400 by 164, we get 8 with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 408404.408
Subtract 1312 from 1400 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
164 can be fit into 880 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 408404.4085
If we take 820 away from 880, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
The number 164 fits into 600 3 times, leaving a remainder of 108.
Use 3 as the next digit of our solution. 
Result so far: 408404.40853
Deduct 492 from 600 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 14:
If we divide 1080 by 164, we get 6 and a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 408404.408536
If we take 984 away from 1080, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 15:
960 divided by 164 is 5 with a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 408404.4085365
Subtract 820 from 960 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 16:
1400 divided by 164 is 8 with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 408404.40853658
If we subtract 1312 from 1400, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final outcome is 408404.40853658, with a leftover of 8.8e-08.
