We look at the division of 518956 by 73 
The aim is to understand the frequency of 73 in 518956.

Step 1:
The number 73 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 73

Advancing to step 2:
When dividing 51 by 73, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 73

Going ahead to step 3:
518 divided by 73 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 511 from 518 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 73

Going ahead to step 4:
When dividing 79 by 73, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtract 73 from 79 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 73

Let's proceed to step 5:
The number 73 fits into 65 0 times, leaving a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 710.0
Subtracting 0 from 65 leaves us with 65.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 73

Let's proceed to step 6:
If we divide 656 by 73, we get 8 and a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 7108.0
If we take 584 away from 656, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 7:
720 divided by 73 is 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 7108.9
Subtract 657 from 720 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 8:
When dividing 630 by 73, we get 8 with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 7108.98
If we subtract 584 from 630, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
73 can be fit into 460 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 7108.986
If we take 438 away from 460, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
When dividing 220 by 73, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 7108.9863
Subtracting 219 from 220 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
When dividing 10 by 73, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7108.9863
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
If we divide 100 by 73, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 7108.986301
If we subtract 73 from 100, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 13:
The number 73 fits into 270 3 times, leaving a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 7108.9863013
If we take 219 away from 270, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 14:
510 divided by 73 is 6 with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 7108.98630136
If we subtract 438 from 510, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 7108.98630136 with a remaining 7.2e-08.
