We look at the division of 131102 by 73 
The aim is to understand the frequency of 73 in 131102.

Advancing to step 1:
1 divided by 73 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 73

Advancing to step 2:
If we divide 13 by 73, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 73

On to step 3:
131 divided by 73 is 1 with a remainder of 58.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 73 from 131, we get 58.
Take the next digit (1) from the dividend and append it to 58, then repeat: 581 / 73

Advancing to step 4:
73 goes into 581 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 70 after subtracting 511 from 581.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 73

Moving on to step 5:
73 can be fit into 700 9 times, resulting in a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
If we subtract 657 from 700, we get 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 73

Step 6:
73 can be fit into 432 5 times, resulting in a remainder of 67.
The next digit of our result is 5. 
Result so far: 1795.0
The remainder is 67 after subtracting 365 from 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 7:
The number 73 fits into 670 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 1795.9
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:
If we divide 130 by 73, we get 1 and a remainder of 57.
The next digit of our result is 1. 
Result so far: 1795.91
Subtracting 73 from 130 leaves us 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.

Moving on to step 9:
570 divided by 73 is 7 with a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 1795.917
Subtract 511 from 570 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.

On to step 10:
590 divided by 73 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1795.9178
The remainder is 6 after subtracting 584 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
If we divide 60 by 73, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1795.9178
If we take 0 away from 60, we end up 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 12:
600 divided by 73 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 1795.917808
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.

Advancing to step 13:
73 goes into 160 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 1795.9178082
Deduct 146 from 160 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
The number 73 fits into 140 1 times, leaving a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 1795.91780821
Subtracting 73 from 140 leaves us 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 1795.91780821 with a balance of 6.7e-08.
