281200 ÷ 18 
The aim is to understand the frequency of 18 in 281200.

Going ahead to step 1:
If we divide 2 by 18, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 18

On to step 2:
The number 18 fits into 28 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 18 from 28 and we're left with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 18

Let's proceed to step 3:
18 goes into 101 5 times with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 90 away from 101, we end up with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 18

Advancing to step 4:
18 goes into 112 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 156.0
If we take 108 away from 112, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 18

Advancing to step 5:
If we divide 40 by 18, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1562.0
Subtract 36 from 40 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 18

Step 6:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 15622.0
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead 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: 15622.2
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.

Going ahead to step 8:
The number 18 fits into 40 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 15622.22
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 quotient of the division is 15622.22, and the remainder is 0.004.
