We're dividing 73819 by 18 
The aim is to understand the frequency of 18 in 73819.

Moving on to step 1:
When dividing 7 by 18, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 18

Moving on to step 2:
The number 18 fits into 73 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 72 from 73 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 18

Advancing to step 3:
18 divided by 18 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Deduct 18 from 18 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 18

Going ahead to step 4:
1 divided by 18 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 410.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 18

Going ahead to step 5:
18 goes into 19 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 4101.0
The remainder is 1 after subtracting 18 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 6:
18 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4101.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
If we divide 100 by 18, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 4101.05
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
18 goes into 100 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 4101.055
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 4101.055, and the remainder is 0.001.
