We're dividing 766002 by 18 
The aim is to understand the frequency of 18 in 766002.

Advancing to step 1:
18 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 18

Advancing 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
Subtract 72 from 76 to get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 18

Step 3:
The number 18 fits into 46 2 times, leaving a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 36 from 46, we get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 18

Going ahead to step 4:
If we divide 100 by 18, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 425.0
Subtracting 90 from 100 leaves us with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 18

Moving on to step 5:
100 divided by 18 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 4255.0
Deduct 90 from 100 and we're left with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 18

Step 6:
102 divided by 18 is 5 with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 42555.0
If we take 90 away from 102, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
18 goes into 120 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 42555.6
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
18 goes into 120 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 42555.66
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 42555.66, and the remainder is 0.012.
