We're dividing 141015 by 39 
The aim is to understand the frequency of 39 in 141015.

Advancing to step 1:
If we divide 1 by 39, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 39

Going ahead to step 2:
14 divided by 39 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 39

Step 3:
141 divided by 39 is 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 117 from 141 leaves us with 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 39

Step 4:
240 divided by 39 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtracting 234 from 240 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 39

Moving on to step 5:
61 divided by 39 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 361.0
Deduct 39 from 61 and we're left with 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 39

Advancing to step 6:
225 divided by 39 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 3615.0
The remainder is 30 after subtracting 195 from 225.
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 7:
The number 39 fits into 300 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 3615.7
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
270 divided by 39 is 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 3615.76
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
If we divide 360 by 39, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 3615.769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
39 goes into 90 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 3615.7692
Subtracting 78 from 90 leaves us 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.

Step 11:
39 can be fit into 120 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3615.76923
Subtracting 117 from 120 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.

Going ahead to step 12:
30 divided by 39 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 3615.76923
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
When dividing 300 by 39, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 3615.7692307
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 14:
270 divided by 39 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 3615.76923076
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 3615.76923076 with a balance of 3.6e-08.
