We look at the division of 868443 by 36 
The aim is to understand the frequency of 36 in 868443.

Moving on to step 1:
36 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 36

Moving on to step 2:
86 divided by 36 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
If we take 72 away from 86, we end up with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 36

Going ahead to step 3:
The number 36 fits into 148 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 144 away from 148, we end up with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 36

On to step 4:
36 goes into 44 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 241.0
Subtract 36 from 44 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 36

Moving on to step 5:
84 divided by 36 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2412.0
If we subtract 72 from 84, we get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 36

Let's proceed to step 6:
123 divided by 36 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 24123.0
The remainder is 15 after subtracting 108 from 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
36 can be fit into 150 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 24123.4
Subtracting 144 from 150 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
When dividing 60 by 36, we get 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 24123.41
Deduct 36 from 60 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
If we divide 240 by 36, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 24123.416
If we subtract 216 from 240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
240 divided by 36 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 24123.4166
If we subtract 216 from 240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 24123.4166, with a leftover of 0.00024.
