We divide 350005 by 18
The aim is to understand the frequency of 18 in 350005.

Moving on to step 1:
18 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 18

Step 2:
18 goes into 35 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 18 from 35 and we're left with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 18

Advancing to step 3:
If we divide 170 by 18, we get 9 and a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 162 from 170 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 18

On to step 4:
The number 18 fits into 80 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 194.0
The remainder is 8 after subtracting 72 from 80.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 18

On to step 5:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1944.0
The remainder is 8 after subtracting 72 from 80.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 18

Moving on to step 6:
18 goes into 85 4 times with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 19444.0
If we take 72 away from 85, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 18, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 19444.7
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 19444.72
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
18 goes into 40 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 19444.722
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 19444.722 with a remaining 0.0004.
