We look at the division of 86281 by 73 
The aim is to understand the frequency of 73 in 86281.

Let's proceed to step 1:
When dividing 8 by 73, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 73

Let's proceed to step 2:
73 can be fit into 86 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 73 from 86 leaves us with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 73

Step 3:
73 can be fit into 132 1 times, resulting in a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 73 from 132 and we're left with 59.
Bring next digit (8) of the dividend behind the 59 and repeat the process: 598 / 73

Moving on to step 4:
When dividing 598 by 73, we get 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
If we take 584 away from 598, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 73

Let's proceed to step 5:
73 can be fit into 141 1 times, resulting in a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 1181.0
If we subtract 73 from 141, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 6:
If we divide 680 by 73, we get 9 and a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 1181.9
Subtract 657 from 680 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
73 goes into 230 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 1181.93
Subtracting 219 from 230 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
If we divide 110 by 73, we get 1 and a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1181.931
The remainder is 37 after subtracting 73 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
73 goes into 370 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1181.9315
The remainder is 5 after subtracting 365 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 73 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 1181.9315
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
73 can be fit into 500 6 times, resulting in a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 1181.931506
Subtracting 438 from 500 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
73 goes into 620 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 1181.9315068
The remainder is 36 after subtracting 584 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
The number 73 fits into 360 4 times, leaving a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 1181.93150684
If we take 292 away from 360, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 1181.93150684 with a remainder of 6.8e-08.
