We divide 793916 by 18
The aim is to understand the frequency of 18 in 793916.

Step 1:
When dividing 7 by 18, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 18

Advancing to step 2:
18 can be fit into 79 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 72 from 79 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 18

On to step 3:
The number 18 fits into 73 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 72 from 73 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 18

Going ahead to step 4:
The number 18 fits into 19 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 441.0
Deduct 18 from 19 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 18

Moving on to step 5:
When dividing 11 by 18, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 4410.0
Subtract 0 from 11 to get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 18

Let's proceed to step 6:
18 goes into 116 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 44106.0
If we subtract 108 from 116, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
18 can be fit into 80 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 44106.4
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 18, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 44106.44
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 44106.44 and a remainder of 0.008.
