We look at the division of 258382 by 73 
The aim is to understand the frequency of 73 in 258382.

Step 1:
When dividing 2 by 73, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 73

Step 2:
If we divide 25 by 73, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 73

Going ahead to step 3:
258 divided by 73 is 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 219 from 258 leaves us with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 73

Advancing to step 4:
73 goes into 393 5 times with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we subtract 365 from 393, we get 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 73

Step 5:
The number 73 fits into 288 3 times, leaving a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 353.0
If we take 219 away from 288, we end up with 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 73

On to step 6:
73 goes into 692 9 times with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 3539.0
Subtract 657 from 692 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
350 divided by 73 is 4 with a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 3539.4
Deduct 292 from 350 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
580 divided by 73 is 7 with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 3539.47
The remainder is 69 after subtracting 511 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
690 divided by 73 is 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 3539.479
The remainder is 33 after subtracting 657 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 10:
The number 73 fits into 330 4 times, leaving a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 3539.4794
If we take 292 away from 330, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
When dividing 380 by 73, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 3539.47945
If we take 365 away from 380, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
If we divide 150 by 73, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 3539.479452
The remainder is 4 after subtracting 146 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
If we divide 40 by 73, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3539.479452
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
73 can be fit into 400 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 3539.47945205
If we take 365 away from 400, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 3539.47945205 with a remainder of 3.5e-08.
