We look at the division of 830348 by 73 
The aim is to understand the frequency of 73 in 830348.

Let's proceed to step 1:
When dividing 8 by 73, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in 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

On to step 2:
83 divided by 73 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 73 away from 83, we end up with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 73

Advancing to step 3:
When dividing 100 by 73, we get 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 73 away from 100, we end up with 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 73

Step 4:
When dividing 273 by 73, we get 3 with a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 113.0
Deduct 219 from 273 and we're left with 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 73

Moving on to step 5:
73 goes into 544 7 times with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 1137.0
If we subtract 511 from 544, we get 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 73

Advancing to step 6:
73 can be fit into 338 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 11374.0
Subtract 292 from 338 to 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.

Step 7:
If we divide 460 by 73, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 11374.6
The remainder is 22 after subtracting 438 from 460.
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 8:
73 goes into 220 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 11374.63
If we take 219 away from 220, we end up 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.

On to step 9:
10 divided by 73 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 11374.63
Subtracting 0 from 10 leaves us 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.

Advancing to step 10:
When dividing 100 by 73, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 11374.6301
Subtract 73 from 100 to 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.

Let's proceed to step 11:
270 divided by 73 is 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 11374.63013
Subtracting 219 from 270 leaves us 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 12:
510 divided by 73 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 11374.630136
If we take 438 away from 510, 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.

Going ahead to step 13:
73 can be fit into 720 9 times, resulting in a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 11374.6301369
If we take 657 away from 720, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 14:
73 can be fit into 630 8 times, resulting in a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 11374.63013698
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.

The final outcome is 11374.63013698, with a leftover of 4.6e-08.
