We look at the division of 77518394 by 930 
The aim is to understand the frequency of 930 in 77518394.

On to step 1:
7 divided by 930 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 930

Step 2:
The number 930 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 930

Advancing to step 3:
930 goes into 775 0 times with a remainder of 775.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 775, we end up with 775.
Take the next digit (1) from the dividend and append it to 775, then repeat: 7751 / 930

Step 4:
930 can be fit into 7751 8 times, resulting in a remainder of 311.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 7440 from 7751 leaves us with 311.
Take the next digit (8) from the dividend and append it to 311, then repeat: 3118 / 930

On to step 5:
930 can be fit into 3118 3 times, resulting in a remainder of 328.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtracting 2790 from 3118 leaves us with 328.
Grab the next digit (3) from the dividend, add it to 328, then carry on: 3283 / 930

Advancing to step 6:
930 can be fit into 3283 3 times, resulting in a remainder of 493.
The next digit of our result is 3. 
Result so far: 833.0
If we subtract 2790 from 3283, we get 493.
Bring next digit (9) of the dividend behind the 493 and repeat the process: 4939 / 930

Going ahead to step 7:
930 can be fit into 4939 5 times, resulting in a remainder of 289.
The number 5 becomes the next digit in our result. 
Result so far: 8335.0
The remainder is 289 after subtracting 4650 from 4939.
Take the next digit (4) from the dividend and append it to 289, then repeat: 2894 / 930

Let's proceed to step 8:
930 goes into 2894 3 times with a remainder of 104.
Record the quotient 3 as the next digit in the result. 
Result so far: 83353.0
The remainder is 104 after subtracting 2790 from 2894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 9:
When dividing 1040 by 930, we get 1 with a remainder of 110.
Use 1 as the next digit of our solution. 
Result so far: 83353.1
The remainder is 110 after subtracting 930 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
930 goes into 1100 1 times with a remainder of 170.
Write down 1 as next digit of the result. 
Result so far: 83353.11
If we take 930 away from 1100, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 83353.11, with a leftover of 0.17.
