We look at the division of 806928 by 73 
The aim is to understand the frequency of 73 in 806928.

Advancing to step 1:
If we divide 8 by 73, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 73

Advancing to step 2:
When dividing 80 by 73, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 73 from 80, we get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 73

Let's proceed to step 3:
If we divide 76 by 73, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 73 from 76, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 73

Let's proceed to step 4:
The number 73 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 110.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 73

Going ahead to step 5:
392 divided by 73 is 5 with a remainder of 27.
Put 5 as the next digit of the answer. 
Result so far: 1105.0
Subtract 365 from 392 to get 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 73

On to step 6:
73 can be fit into 278 3 times, resulting in a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 11053.0
Subtract 219 from 278 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
73 goes into 590 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 11053.8
If we subtract 584 from 590, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 73, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 11053.8
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
73 can be fit into 600 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 11053.808
If we subtract 584 from 600, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
73 goes into 160 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 11053.8082
The remainder is 14 after subtracting 146 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
When dividing 140 by 73, we get 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 11053.80821
If we subtract 73 from 140, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 12:
73 can be fit into 670 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 11053.808219
Subtracting 657 from 670 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
The number 73 fits into 130 1 times, leaving a remainder of 57.
The next digit of our result is 1. 
Result so far: 11053.8082191
Subtract 73 from 130 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 14:
If we divide 570 by 73, we get 7 and a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 11053.80821917
Deduct 511 from 570 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 11053.80821917, with a leftover of 5.9e-08.
