We divide 432922 by 18
The aim is to understand the frequency of 18 in 432922.

Going ahead to step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 18

Let's proceed to step 2:
If we divide 43 by 18, we get 2 and a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 36 from 43, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 18

Going ahead to step 3:
18 goes into 72 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we subtract 72 from 72, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 18

On to step 4:
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: 240.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 18

Moving on to step 5:
92 divided by 18 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 2405.0
The remainder is 2 after subtracting 90 from 92.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 18

Moving on to step 6:
The number 18 fits into 22 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 24051.0
Deduct 18 from 22 and we're left 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.

Moving on to step 7:
When dividing 40 by 18, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 24051.2
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
18 goes into 40 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 24051.22
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 24051.22 with a remainder of 0.004.
