We divide 69966893 by 18
The aim is to understand the frequency of 18 in 69966893.

Advancing to step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 18

Advancing to step 2:
69 divided by 18 is 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 54 away from 69, we end up with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 18

Let's proceed to step 3:
18 can be fit into 159 8 times, resulting in a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we take 144 away from 159, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 18

Step 4:
156 divided by 18 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 388.0
Subtracting 144 from 156 leaves us with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 18

Step 5:
The number 18 fits into 126 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 3887.0
Subtract 126 from 126 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 18

Let's proceed to step 6:
8 divided by 18 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 38870.0
Subtract 0 from 8 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 18

On to step 7:
89 divided by 18 is 4 with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 388704.0
Subtract 72 from 89 to get 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 18

On to step 8:
When dividing 173 by 18, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 3887049.0
The remainder is 11 after subtracting 162 from 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
18 can be fit into 110 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 3887049.6
If we subtract 108 from 110, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
20 divided by 18 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 3887049.61
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
18 goes into 20 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 3887049.611
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 3887049.611 with a balance of 0.0002.
