We look at the division of 75209 by 73 
The aim is to understand the frequency of 73 in 75209.

Let's proceed to step 1:
When dividing 7 by 73, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 73

Let's proceed to step 2:
The number 73 fits into 75 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 73 from 75.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 73

Let's proceed to step 3:
22 divided by 73 is 0 with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 22 after subtracting 0 from 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 73

Moving on to step 4:
If we divide 220 by 73, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
The remainder is 1 after subtracting 219 from 220.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 73

Advancing to step 5:
If we divide 19 by 73, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 1030.0
The remainder is 19 after subtracting 0 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 6:
190 divided by 73 is 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 1030.2
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.

Going ahead to step 7:
The number 73 fits into 440 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 1030.26
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.

Going ahead to step 8:
20 divided by 73 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1030.26
If we take 0 away from 20, we end up with 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 9:
The number 73 fits into 200 2 times, leaving a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 1030.2602
If we take 146 away from 200, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
If we divide 540 by 73, we get 7 and a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 1030.26027
Subtract 511 from 540 to 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.

Going ahead to step 11:
If we divide 290 by 73, we get 3 and a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 1030.260273
The remainder is 71 after subtracting 219 from 290.
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 12:
When dividing 710 by 73, we get 9 with a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 1030.2602739
If we take 657 away from 710, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 13:
73 goes into 530 7 times with a remainder of 19.
The next digit of our result is 7. 
Result so far: 1030.26027397
Subtract 511 from 530 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 1030.26027397 with a balance of 1.9e-08.
