We look at the division of 63485 by 18 
The aim is to understand the frequency of 18 in 63485.

Moving on to step 1:
When dividing 6 by 18, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 18

Let's proceed to step 2:
63 divided by 18 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 54 from 63 and we're left with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 18

Going ahead to step 3:
The number 18 fits into 94 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 4 after subtracting 90 from 94.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 18

On to step 4:
The number 18 fits into 48 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 352.0
Subtract 36 from 48 to get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 18

Going ahead to step 5:
18 goes into 125 6 times with a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 3526.0
The remainder is 17 after subtracting 108 from 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 6:
18 can be fit into 170 9 times, resulting in a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 3526.9
Subtracting 162 from 170 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
80 divided by 18 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 3526.94
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
18 goes into 80 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3526.944
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 3526.944 with a balance of 0.0008.
