366439 divided by 73 
The aim is to understand the frequency of 73 in 366439.

Let's proceed to step 1:
The number 73 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 73

Moving on to step 2:
73 goes into 36 0 times with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 73

Advancing to step 3:
366 divided by 73 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 365 from 366 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 73

Moving on to step 4:
73 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we subtract 0 from 14, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 73

Going ahead to step 5:
73 goes into 143 1 times with a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 501.0
If we subtract 73 from 143, we get 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 73

On to step 6:
The number 73 fits into 709 9 times, leaving a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 5019.0
Deduct 657 from 709 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
520 divided by 73 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 5019.7
Subtract 511 from 520 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
73 goes into 90 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 5019.71
Deduct 73 from 90 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
73 can be fit into 170 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 5019.712
If we take 146 away from 170, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
73 can be fit into 240 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 5019.7123
Subtract 219 from 240 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
210 divided by 73 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 5019.71232
If we take 146 away from 210, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
73 can be fit into 640 8 times, resulting in a remainder of 56.
The next digit of our result is 8. 
Result so far: 5019.712328
Subtract 584 from 640 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
560 divided by 73 is 7 with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 5019.7123287
The remainder is 49 after subtracting 511 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 14:
The number 73 fits into 490 6 times, leaving a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 5019.71232876
If we take 438 away from 490, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 5019.71232876 with a balance of 5.2e-08.
