We look at the division of 966015 by 73 
The aim is to understand the frequency of 73 in 966015.

Advancing to step 1:
The number 73 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 73

Let's proceed to step 2:
The number 73 fits into 96 1 times, leaving a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 73 from 96 to get 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 73

Advancing to step 3:
When dividing 236 by 73, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 17 after subtracting 219 from 236.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 73

Step 4:
73 goes into 170 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 132.0
The remainder is 24 after subtracting 146 from 170.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 73

Let's proceed to step 5:
241 divided by 73 is 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 1323.0
Subtracting 219 from 241 leaves us with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 73

Moving on to step 6:
When dividing 225 by 73, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 13233.0
Subtracting 219 from 225 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
73 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 13233.0
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.

Going ahead to step 8:
73 goes into 600 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 13233.08
Deduct 584 from 600 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
The number 73 fits into 160 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 13233.082
Subtracting 146 from 160 leaves us 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.

Let's proceed to step 10:
When dividing 140 by 73, we get 1 with a remainder of 67.
The next digit of our result is 1. 
Result so far: 13233.0821
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 11:
73 goes into 670 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 13233.08219
Subtract 657 from 670 to 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 12:
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: 13233.082191
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 13:
The number 73 fits into 570 7 times, leaving a remainder of 59.
The next digit of our result is 7. 
Result so far: 13233.0821917
The remainder is 59 after subtracting 511 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 14:
The number 73 fits into 590 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 13233.08219178
Deduct 584 from 590 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 13233.08219178 with a remainder of 6e-09.
