We look at the division of 269815 by 73 
The aim is to understand the frequency of 73 in 269815.

Let's proceed to step 1:
73 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 73

Let's proceed to step 2:
When dividing 26 by 73, we get 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 73

Step 3:
The number 73 fits into 269 3 times, leaving a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 219 from 269 and we're left with 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 73

Let's proceed to step 4:
73 can be fit into 508 6 times, resulting in a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 70 after subtracting 438 from 508.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 73

Going ahead to step 5:
701 divided by 73 is 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 369.0
Subtracting 657 from 701 leaves us with 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 73

On to step 6:
If we divide 445 by 73, we get 6 and a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 3696.0
Deduct 438 from 445 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
73 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 3696.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
If we divide 700 by 73, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 3696.09
Subtracting 657 from 700 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
The number 73 fits into 430 5 times, leaving a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 3696.095
If we subtract 365 from 430, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 10:
73 goes into 650 8 times with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 3696.0958
If we take 584 away from 650, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
73 can be fit into 660 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 3696.09589
Deduct 657 from 660 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
When dividing 30 by 73, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 3696.09589
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
The number 73 fits into 300 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 3696.0958904
Deduct 292 from 300 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
If we divide 80 by 73, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 3696.09589041
Subtracting 73 from 80 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 3696.09589041 with a remainder of 7e-09.
