355846 divided by 18 
The aim is to understand the frequency of 18 in 355846.

Moving on to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 18

Step 2:
The number 18 fits into 35 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 18 from 35, we get 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 18

Going ahead to step 3:
175 divided by 18 is 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 13 after subtracting 162 from 175.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 18

Step 4:
If we divide 138 by 18, we get 7 and a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 197.0
Subtract 126 from 138 to get 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 18

Advancing to step 5:
The number 18 fits into 124 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 1976.0
The remainder is 16 after subtracting 108 from 124.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 18

Let's proceed to step 6:
If we divide 166 by 18, we get 9 and a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 19769.0
Subtract 162 from 166 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.

Moving on to step 7:
If we divide 40 by 18, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 19769.2
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.

Moving on to step 8:
18 can be fit into 40 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 19769.22
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.

The quotient of the division is 19769.22, and the remainder is 0.004.
