We look at the division of 782409 by 36 
The aim is to understand the frequency of 36 in 782409.

Going ahead to step 1:
If we divide 7 by 36, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 36

On to step 2:
36 goes into 78 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 72 away from 78, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 36

Advancing to step 3:
36 can be fit into 62 1 times, resulting in a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 36 from 62 leaves us with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 36

Let's proceed to step 4:
36 can be fit into 264 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
Subtracting 252 from 264 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 36

Advancing to step 5:
36 goes into 120 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 2173.0
If we take 108 away from 120, we end up with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 36

Advancing to step 6:
36 goes into 129 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 21733.0
The remainder is 21 after subtracting 108 from 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 36, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 21733.5
If we subtract 180 from 210, 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.

Going ahead to step 8:
If we divide 300 by 36, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 21733.58
If we take 288 away from 300, 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.

Going ahead to step 9:
36 can be fit into 120 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 21733.583
The remainder is 12 after subtracting 108 from 120.
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 10:
The number 36 fits into 120 3 times, leaving a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 21733.5833
Subtract 108 from 120 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.

The quotient of the division is 21733.5833, and the remainder is 0.00012.
