203415 divided by 39 
The aim is to understand the frequency of 39 in 203415.

Moving on to step 1:
39 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 39

Moving on to step 2:
39 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 39

Step 3:
If we divide 203 by 39, we get 5 and a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 195 from 203, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 39

Let's proceed to step 4:
When dividing 84 by 39, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 52.0
If we take 78 away from 84, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 39

Going ahead to step 5:
39 goes into 61 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 521.0
If we subtract 39 from 61, we get 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 39

Step 6:
39 goes into 225 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 5215.0
If we take 195 away from 225, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
300 divided by 39 is 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 5215.7
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.

Advancing to step 8:
39 can be fit into 270 6 times, resulting in a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 5215.76
The remainder is 36 after subtracting 234 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
If we divide 360 by 39, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 5215.769
If we subtract 351 from 360, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
The number 39 fits into 90 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 5215.7692
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.

Advancing to step 11:
When dividing 120 by 39, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 5215.76923
If we take 117 away from 120, we end up 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.

On to step 12:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 5215.76923
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.

Advancing to step 13:
The number 39 fits into 300 7 times, leaving a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 5215.7692307
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.

Moving on to step 14:
270 divided by 39 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 5215.76923076
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 5215.76923076 with a balance of 3.6e-08.
