418347 divided by 18 
The aim is to understand the frequency of 18 in 418347.

Let's proceed to step 1:
The number 18 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 18

Step 2:
If we divide 41 by 18, we get 2 and a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 36 from 41 to get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 18

Going ahead to step 3:
18 can be fit into 58 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 54 from 58, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 18

Step 4:
18 goes into 43 2 times with a remainder of 7.
The next digit of our result is 2. 
Result so far: 232.0
Deduct 36 from 43 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 18

Going ahead to step 5:
18 can be fit into 74 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 2324.0
The remainder is 2 after subtracting 72 from 74.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 18

Let's proceed to step 6:
27 divided by 18 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 23241.0
Subtract 18 from 27 to 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.

Moving on to step 7:
When dividing 90 by 18, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 23241.5
Subtracting 90 from 90 leaves us 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.

Let's proceed to step 8:
18 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23241.5
Subtracting 0 from 0 leaves us 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.

Step 9:
0 divided by 18 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 23241.5
If we subtract 0 from 0, we 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.

The quotient of the division is 23241.5, and the remainder is 0.0.
