Let's divide 760623 by 18
The aim is to understand the frequency of 18 in 760623.

Advancing to step 1:
18 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 18

Going ahead to step 2:
76 divided by 18 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 72 from 76 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 18

On to step 3:
The number 18 fits into 40 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtract 36 from 40 to get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 18

Advancing to step 4:
When dividing 46 by 18, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 422.0
If we subtract 36 from 46, we get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 18

Going ahead to step 5:
18 can be fit into 102 5 times, resulting in a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 4225.0
Deduct 90 from 102 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 18

Let's proceed to step 6:
18 can be fit into 123 6 times, resulting in a remainder of 15.
The next digit of our result is 6. 
Result so far: 42256.0
Subtract 108 from 123 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
When dividing 150 by 18, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 42256.8
If we subtract 144 from 150, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
60 divided by 18 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 42256.83
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
18 can be fit into 60 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 42256.833
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 42256.833 and a remainder of 0.0006.
