We're dividing 406750 by 73 
The aim is to understand the frequency of 73 in 406750.

Going ahead to step 1:
If we divide 4 by 73, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 73

Moving on to step 2:
73 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 73

On to step 3:
406 divided by 73 is 5 with a remainder of 41.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 365 from 406 and we're left with 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 73

Going ahead to step 4:
If we divide 417 by 73, we get 5 and a remainder of 52.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Deduct 365 from 417 and we're left with 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 73

On to step 5:
The number 73 fits into 525 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 557.0
Subtract 511 from 525 to get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 73

Step 6:
When dividing 140 by 73, we get 1 with a remainder of 67.
The next digit of our result is 1. 
Result so far: 5571.0
Deduct 73 from 140 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
If we divide 670 by 73, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 5571.9
If we subtract 657 from 670, we get 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 8:
73 can be fit into 130 1 times, resulting in a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 5571.91
If we take 73 away from 130, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 9:
73 can be fit into 570 7 times, resulting in a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 5571.917
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.

Advancing to step 10:
73 goes into 590 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 5571.9178
Subtract 584 from 590 to 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.

Moving on to step 11:
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: 5571.9178
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
73 goes into 600 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 5571.917808
Subtract 584 from 600 to 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.

On to step 13:
73 goes into 160 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 5571.9178082
Subtract 146 from 160 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
73 goes into 140 1 times with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 5571.91780821
If we take 73 away from 140, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

In conclusion, the division gives 5571.91780821 with a balance of 6.7e-08.
