We divide 429553 by 18
The aim is to understand the frequency of 18 in 429553.

Step 1:
4 divided by 18 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 18

Advancing to step 2:
18 can be fit into 42 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 36 away from 42, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 18

On to step 3:
18 can be fit into 69 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 54 away from 69, we end up with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 18

Step 4:
18 can be fit into 155 8 times, resulting in a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 238.0
Deduct 144 from 155 and we're left with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 18

On to step 5:
18 goes into 115 6 times with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 2386.0
Subtract 108 from 115 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 18

On to step 6:
73 divided by 18 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 23864.0
If we subtract 72 from 73, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 18 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 23864.0
Subtract 0 from 10 to get 10.
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 8:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 23864.05
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
If we divide 100 by 18, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 23864.055
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.

In conclusion, the division gives 23864.055 with a balance of 0.001.
