72914383 divided by 394 
The aim is to understand the frequency of 394 in 72914383.

Going ahead to step 1:
7 divided by 394 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 394

Moving on to step 2:
If we divide 72 by 394, we get 0 and a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 394

Let's proceed to step 3:
When dividing 729 by 394, we get 1 with a remainder of 335.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 394 from 729, we get 335.
Append the next digit (1) from the dividend to 335 and continue with: 3351 / 394

Step 4:
The number 394 fits into 3351 8 times, leaving a remainder of 199.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 3152 from 3351 to get 199.
Fetch the next digit (4) from the dividend, attach it to 199 and continue: 1994 / 394

Moving on to step 5:
If we divide 1994 by 394, we get 5 and a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 185.0
The remainder is 24 after subtracting 1970 from 1994.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 394

Step 6:
394 can be fit into 243 0 times, resulting in a remainder of 243.
Use 0 as the next digit of our solution. 
Result so far: 1850.0
The remainder is 243 after subtracting 0 from 243.
Take the next digit (8) from the dividend and append it to 243, then repeat: 2438 / 394

Going ahead to step 7:
394 goes into 2438 6 times with a remainder of 74.
The next digit of our result is 6. 
Result so far: 18506.0
Subtracting 2364 from 2438 leaves us with 74.
Append the next digit (3) from the dividend to 74 and continue with: 743 / 394

Let's proceed to step 8:
The number 394 fits into 743 1 times, leaving a remainder of 349.
The next digit of our result is 1. 
Result so far: 185061.0
Subtracting 394 from 743 leaves us with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 9:
The number 394 fits into 3490 8 times, leaving a remainder of 338.
Use 8 as the next digit of our solution. 
Result so far: 185061.8
The remainder is 338 after subtracting 3152 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 10:
If we divide 3380 by 394, we get 8 and a remainder of 228.
Put 8 as the next digit of the answer. 
Result so far: 185061.88
If we subtract 3152 from 3380, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The final result is 185061.88 with a remainder of 0.228.
