376036 ÷ 18 
The aim is to understand the frequency of 18 in 376036.

Step 1:
The number 18 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 18

Going ahead to step 2:
If we divide 37 by 18, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 1 after subtracting 36 from 37.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 18

Advancing to step 3:
If we divide 16 by 18, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 16, we get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 18

Step 4:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 208.0
If we take 144 away from 160, we end up with 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 18

On to step 5:
When dividing 163 by 18, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 2089.0
If we subtract 162 from 163, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 18

Step 6:
18 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 20890.0
Subtract 0 from 16 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
160 divided by 18 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 20890.8
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
The number 18 fits into 160 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 20890.88
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 20890.88 with a remainder of 0.016.
