We're dividing 20485504 by 39 
The aim is to understand the frequency of 39 in 20485504.

Let's proceed to step 1:
2 divided by 39 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 39

Going ahead to step 2:
39 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 39

Moving on to step 3:
39 can be fit into 204 5 times, resulting in a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 195 away from 204, we end up with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 39

Going ahead to step 4:
98 divided by 39 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 52.0
The remainder is 20 after subtracting 78 from 98.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 39

On to step 5:
39 can be fit into 205 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 525.0
Subtracting 195 from 205 leaves us with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 39

Advancing to step 6:
105 divided by 39 is 2 with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 5252.0
If we subtract 78 from 105, we get 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 39

Advancing to step 7:
If we divide 270 by 39, we get 6 and a remainder of 36.
The next digit of our result is 6. 
Result so far: 52526.0
Subtracting 234 from 270 leaves us with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 39

Let's proceed to step 8:
39 goes into 364 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 525269.0
If we take 351 away from 364, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
39 can be fit into 130 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 525269.3
Subtracting 117 from 130 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
If we divide 130 by 39, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 525269.33
Subtracting 117 from 130 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 525269.33 with a remaining 0.013.
