93073923 ÷ 18 
The aim is to understand the frequency of 18 in 93073923.

Advancing to step 1:
18 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 18

Going ahead to step 2:
The number 18 fits into 93 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 90 from 93 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 18

Let's proceed to step 3:
When dividing 30 by 18, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 18 from 30 and we're left with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 18

On to step 4:
When dividing 127 by 18, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 517.0
Deduct 126 from 127 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 18

Advancing to step 5:
If we divide 13 by 18, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 5170.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 18

On to step 6:
When dividing 139 by 18, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 51707.0
Subtracting 126 from 139 leaves us with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 18

Advancing to step 7:
The number 18 fits into 132 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 517077.0
If we take 126 away from 132, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 18

Going ahead to step 8:
63 divided by 18 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 5170773.0
If we subtract 54 from 63, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
90 divided by 18 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5170773.5
The remainder is 0 after subtracting 90 from 90.
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 10:
18 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5170773.5
Deduct 0 from 0 and we're left 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.

Moving on to step 11:
18 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5170773.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 5170773.5 and a remainder of 0.0.
