Let's divide 18090 by 36
The aim is to understand the frequency of 36 in 18090.

Advancing to step 1:
When dividing 1 by 36, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 36

Step 2:
18 divided by 36 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 36

Advancing to step 3:
When dividing 180 by 36, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
If we take 180 away from 180, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 36

Step 4:
The number 36 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 50.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 36

Moving on to step 5:
When dividing 90 by 36, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 502.0
Subtract 72 from 90 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 6:
36 goes into 180 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 502.5
If we take 180 away from 180, 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.

Going ahead to step 7:
The number 36 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 502.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
36 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 502.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 502.5, and the remainder is 0.0.
