We look at the division of 868248 by 73 
The aim is to understand the frequency of 73 in 868248.

Step 1:
8 divided by 73 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 73

Advancing to step 2:
When dividing 86 by 73, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 73 from 86 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 73

Step 3:
138 divided by 73 is 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 73 from 138, we get 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 73

On to step 4:
652 divided by 73 is 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Deduct 584 from 652 and we're left with 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 73

Moving on to step 5:
If we divide 684 by 73, we get 9 and a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 1189.0
If we take 657 away from 684, we end up with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 73

Going ahead to step 6:
When dividing 278 by 73, we get 3 with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 11893.0
If we subtract 219 from 278, we 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.

Advancing to step 7:
590 divided by 73 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 11893.8
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.

Let's proceed to step 8:
73 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 11893.8
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

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: 11893.808
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.

Going ahead to step 10:
160 divided by 73 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 11893.8082
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.

Going ahead to step 11:
140 divided by 73 is 1 with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 11893.80821
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.

Going ahead to step 12:
The number 73 fits into 670 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 11893.808219
Deduct 657 from 670 and we're left 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.

Advancing to step 13:
When dividing 130 by 73, we get 1 with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 11893.8082191
Deduct 73 from 130 and we're left 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.

Going ahead to step 14:
The number 73 fits into 570 7 times, leaving a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 11893.80821917
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.

After the division, we end up with 11893.80821917 and a remainder of 5.9e-08.
