Let's divide 381531 by 36
The aim is to understand the frequency of 36 in 381531.

Going ahead to step 1:
When dividing 3 by 36, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 36

Advancing to step 2:
If we divide 38 by 36, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 36 from 38.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 36

On to step 3:
36 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 36

Step 4:
215 divided by 36 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
If we take 180 away from 215, we end up with 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 36

Advancing to step 5:
When dividing 353 by 36, we get 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 1059.0
If we subtract 324 from 353, we get 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 36

Step 6:
291 divided by 36 is 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 10598.0
Subtracting 288 from 291 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
The number 36 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 10598.0
The remainder is 30 after subtracting 0 from 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 8:
300 divided by 36 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 10598.08
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 9:
120 divided by 36 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 10598.083
Deduct 108 from 120 and we're left 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.

Advancing to step 10:
120 divided by 36 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 10598.0833
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.

Our division results in 10598.0833 with a remaining 0.00012.
