138220 divided by 36 
The aim is to understand the frequency of 36 in 138220.

Let's proceed to step 1:
If we divide 1 by 36, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 36

Going ahead to step 2:
The number 36 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 36

Let's proceed to step 3:
If we divide 138 by 36, we get 3 and a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 108 from 138 to get 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 36

Let's proceed to step 4:
The number 36 fits into 302 8 times, leaving a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
The remainder is 14 after subtracting 288 from 302.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 36

Moving on to step 5:
36 goes into 142 3 times with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 383.0
If we subtract 108 from 142, we get 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 36

Moving on to step 6:
36 can be fit into 340 9 times, resulting in a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 3839.0
Subtracting 324 from 340 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
When dividing 160 by 36, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 3839.4
If we subtract 144 from 160, we 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.

Let's proceed to step 8:
160 divided by 36 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 3839.44
Deduct 144 from 160 and we're left with 16.
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 outcome is 3839.44, with a leftover of 0.016.
