We look at the division of 763902 by 18 
The aim is to understand the frequency of 18 in 763902.

Step 1:
18 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 18

Going ahead to step 2:
18 can be fit into 76 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 72 from 76, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 18

On to step 3:
43 divided by 18 is 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 36 from 43 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 18

Step 4:
If we divide 79 by 18, we get 4 and a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 424.0
If we take 72 away from 79, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 18

Let's proceed to step 5:
18 goes into 70 3 times with a remainder of 16.
The next digit of our result is 3. 
Result so far: 4243.0
Subtract 54 from 70 to get 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 18

Let's proceed to step 6:
The number 18 fits into 162 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 42439.0
If we take 162 away from 162, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
18 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 42439.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42439.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 42439.0 with a balance of 0.0.
