We look at the division of 39972548 by 36 
The aim is to understand the frequency of 36 in 39972548.

Let's proceed to step 1:
The number 36 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 36

Moving on to step 2:
If we divide 39 by 36, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 36 away from 39, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 36

On to step 3:
If we divide 39 by 36, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 36 from 39 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 36

Going ahead to step 4:
36 goes into 37 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 111.0
Subtracting 36 from 37 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 36

Step 5:
The number 36 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 1110.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 36

Step 6:
125 divided by 36 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 11103.0
Subtract 108 from 125 to get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 36

Going ahead to step 7:
36 can be fit into 174 4 times, resulting in a remainder of 30.
The next digit of our result is 4. 
Result so far: 111034.0
If we subtract 144 from 174, we get 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 36

Going ahead to step 8:
If we divide 308 by 36, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 1110348.0
If we take 288 away from 308, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 36, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1110348.5
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
If we divide 200 by 36, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1110348.55
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 1110348.55 with a balance of 0.02.
