We look at the division of 12819 by 36 
The aim is to understand the frequency of 36 in 12819.

Moving on to step 1:
1 divided by 36 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 36

Going ahead to step 2:
36 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 36

On to step 3:
36 goes into 128 3 times with a remainder of 20.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 108 from 128 to get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 36

On to step 4:
The number 36 fits into 201 5 times, leaving a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 180 from 201 and we're left with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 36

On to step 5:
The number 36 fits into 219 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 356.0
Subtract 216 from 219 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 6:
The number 36 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 356.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
300 divided by 36 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 356.08
Subtract 288 from 300 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
36 can be fit into 120 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 356.083
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
36 goes into 120 3 times with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 356.0833
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 356.0833, with a leftover of 0.00012.
