We're dividing 387791 by 73 
The aim is to understand the frequency of 73 in 387791.

Advancing to step 1:
If we divide 3 by 73, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 73

Step 2:
The number 73 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 73

Moving on to step 3:
If we divide 387 by 73, we get 5 and a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 365 from 387 and we're left with 22.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 73

Going ahead to step 4:
If we divide 227 by 73, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 53.0
Subtract 219 from 227 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 73

Step 5:
89 divided by 73 is 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 531.0
Deduct 73 from 89 and we're left with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 73

Step 6:
When dividing 161 by 73, we get 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 5312.0
If we take 146 away from 161, 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.

Step 7:
If we divide 150 by 73, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 5312.2
Subtracting 146 from 150 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 73 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5312.2
The remainder is 40 after subtracting 0 from 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 9:
73 goes into 400 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 5312.205
If we subtract 365 from 400, we 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.

Going ahead to step 10:
The number 73 fits into 350 4 times, leaving a remainder of 58.
The next digit of our result is 4. 
Result so far: 5312.2054
Subtract 292 from 350 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
73 goes into 580 7 times with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 5312.20547
Subtract 511 from 580 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 12:
690 divided by 73 is 9 with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 5312.205479
Deduct 657 from 690 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 13:
When dividing 330 by 73, we get 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 5312.2054794
Subtracting 292 from 330 leaves us 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.

Let's proceed to step 14:
73 can be fit into 380 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 5312.20547945
Subtracting 365 from 380 leaves us 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.

The final result is 5312.20547945 with a remainder of 1.5e-08.
