73121823 ÷ 164 
The aim is to understand the frequency of 164 in 73121823.

Moving on to step 1:
When dividing 7 by 164, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 164

On to step 2:
164 goes into 73 0 times with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 164

On to step 3:
When dividing 731 by 164, we get 4 with a remainder of 75.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 656 from 731 and we're left with 75.
Append the next digit (2) from the dividend to 75 and continue with: 752 / 164

Advancing to step 4:
When dividing 752 by 164, we get 4 with a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 44.0
The remainder is 96 after subtracting 656 from 752.
Fetch the next digit (1) from the dividend, attach it to 96 and continue: 961 / 164

On to step 5:
164 can be fit into 961 5 times, resulting in a remainder of 141.
Record the quotient 5 as the next digit in the result. 
Result so far: 445.0
Subtract 820 from 961 to get 141.
Bring next digit (8) of the dividend behind the 141 and repeat the process: 1418 / 164

Going ahead to step 6:
The number 164 fits into 1418 8 times, leaving a remainder of 106.
The number 8 becomes the next digit in our result. 
Result so far: 4458.0
Subtract 1312 from 1418 to get 106.
Include the next digit (2) from the dividend after 106, then repeat: 1062 / 164

On to step 7:
The number 164 fits into 1062 6 times, leaving a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 44586.0
Deduct 984 from 1062 and we're left with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 164

Going ahead to step 8:
164 goes into 783 4 times with a remainder of 127.
The next digit of our result is 4. 
Result so far: 445864.0
If we subtract 656 from 783, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 9:
1270 divided by 164 is 7 with a remainder of 122.
Use 7 as the next digit of our solution. 
Result so far: 445864.7
Deduct 1148 from 1270 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 10:
1220 divided by 164 is 7 with a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 445864.77
Subtract 1148 from 1220 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 445864.77 and a remainder of 0.072.
