Let's divide 64123 by 73
The aim is to understand the frequency of 73 in 64123.

On to step 1:
73 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 73

Moving on to step 2:
73 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 73

Advancing to step 3:
The number 73 fits into 641 8 times, leaving a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 584 away from 641, we end up with 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 73

Going ahead to step 4:
73 can be fit into 572 7 times, resulting in a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we take 511 away from 572, we end up with 61.
Include the next digit (3) from the dividend after 61, then repeat: 613 / 73

Step 5:
If we divide 613 by 73, we get 8 and a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 878.0
If we take 584 away from 613, we end up 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 6:
290 divided by 73 is 3 with a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 878.3
Subtract 219 from 290 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
710 divided by 73 is 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 878.39
Subtract 657 from 710 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 8:
If we divide 530 by 73, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 878.397
The remainder is 19 after subtracting 511 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
If we divide 190 by 73, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 878.3972
Subtracting 146 from 190 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
The number 73 fits into 440 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 878.39726
Subtract 438 from 440 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
The number 73 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 878.39726
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
The number 73 fits into 200 2 times, leaving a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 878.3972602
Subtract 146 from 200 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
If we divide 540 by 73, we get 7 and a remainder of 29.
The next digit of our result is 7. 
Result so far: 878.39726027
If we subtract 511 from 540, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 878.39726027, with a leftover of 2.9e-08.
