735856 divided by 18 
The aim is to understand the frequency of 18 in 735856.

Let's proceed to step 1:
When dividing 7 by 18, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 18

Moving on to step 2:
18 goes into 73 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 72 from 73, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 18

Advancing to step 3:
If we divide 15 by 18, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 15 to get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 18

Advancing to step 4:
158 divided by 18 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 408.0
The remainder is 14 after subtracting 144 from 158.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 18

Moving on to step 5:
18 goes into 145 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 4088.0
If we subtract 144 from 145, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 18

Moving on to step 6:
16 divided by 18 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 40880.0
Subtracting 0 from 16 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
18 goes into 160 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 40880.8
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
When dividing 160 by 18, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 40880.88
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 40880.88 with a remaining 0.016.
