We look at the division of 830499 by 73 
The aim is to understand the frequency of 73 in 830499.

Going ahead to step 1:
When dividing 8 by 73, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 73

Let's proceed to step 2:
73 goes into 83 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 73 from 83 to get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 73

Step 3:
The number 73 fits into 100 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 73 from 100 leaves us with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 73

Moving on to step 4:
73 can be fit into 274 3 times, resulting in a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Deduct 219 from 274 and we're left with 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 73

Advancing to step 5:
When dividing 559 by 73, we get 7 with a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 1137.0
Subtracting 511 from 559 leaves us with 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 73

Moving on to step 6:
73 goes into 489 6 times with a remainder of 51.
The next digit of our result is 6. 
Result so far: 11376.0
If we take 438 away from 489, 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.

On to step 7:
If we divide 510 by 73, we get 6 and a remainder of 72.
The next digit of our result is 6. 
Result so far: 11376.6
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.

Let's proceed to step 8:
720 divided by 73 is 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 11376.69
If we subtract 657 from 720, we 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.

Advancing to step 9:
73 can be fit into 630 8 times, resulting in a remainder of 46.
The next digit of our result is 8. 
Result so far: 11376.698
Subtracting 584 from 630 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
73 can be fit into 460 6 times, resulting in a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 11376.6986
If we subtract 438 from 460, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
73 goes into 220 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 11376.69863
Subtract 219 from 220 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
73 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 11376.69863
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
73 can be fit into 100 1 times, resulting in a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 11376.6986301
Deduct 73 from 100 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 14:
The number 73 fits into 270 3 times, leaving a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 11376.69863013
The remainder is 51 after subtracting 219 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 11376.69863013, with a leftover of 5.1e-08.
