57923470 divided by 18 
The aim is to understand the frequency of 18 in 57923470.

Let's proceed to step 1:
If we divide 5 by 18, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 18

Advancing to step 2:
57 divided by 18 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 3 after subtracting 54 from 57.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 18

Step 3:
18 can be fit into 39 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 32.0
Subtract 36 from 39 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 18

Let's proceed to step 4:
32 divided by 18 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 321.0
If we take 18 away from 32, we end up with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 18

On to step 5:
The number 18 fits into 143 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 3217.0
If we take 126 away from 143, we end up with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 18

Step 6:
When dividing 174 by 18, we get 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 32179.0
Subtracting 162 from 174 leaves us with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 18

Going ahead to step 7:
127 divided by 18 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 321797.0
If we subtract 126 from 127, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 18

Moving on to step 8:
When dividing 10 by 18, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3217970.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 18, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3217970.5
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 3217970.55
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 3217970.55 and a remainder of 0.01.
