463671 ÷ 18 
The aim is to understand the frequency of 18 in 463671.

On to step 1:
4 divided by 18 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 18

Step 2:
46 divided by 18 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 36 from 46 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 18

Advancing to step 3:
When dividing 103 by 18, we get 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 90 from 103 to get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 18

Going ahead to step 4:
When dividing 136 by 18, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 257.0
Deduct 126 from 136 and we're left with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 18

Advancing to step 5:
107 divided by 18 is 5 with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 2575.0
If we subtract 90 from 107, we get 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 18

Let's proceed to step 6:
If we divide 171 by 18, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 25759.0
If we subtract 162 from 171, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
18 can be fit into 90 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 25759.5
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
If we divide 0 by 18, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25759.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 18 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25759.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 25759.5 and a remainder of 0.0.
