We're dividing 239828 by 39 
The aim is to understand the frequency of 39 in 239828.

Let's proceed to step 1:
If we divide 2 by 39, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 39

Let's proceed to step 2:
The number 39 fits into 23 0 times, leaving a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 39

Step 3:
39 goes into 239 6 times with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 234 from 239 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 39

On to step 4:
39 can be fit into 58 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
If we subtract 39 from 58, we get 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 39

On to step 5:
When dividing 192 by 39, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 614.0
Deduct 156 from 192 and we're left with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 39

Advancing to step 6:
368 divided by 39 is 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 6149.0
Deduct 351 from 368 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 6149.4
Deduct 156 from 170 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
When dividing 140 by 39, we get 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 6149.43
Deduct 117 from 140 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
230 divided by 39 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 6149.435
Deduct 195 from 230 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
If we divide 350 by 39, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 6149.4358
If we take 312 away from 350, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 6149.43589
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
290 divided by 39 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 6149.435897
Subtracting 273 from 290 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 13:
39 can be fit into 170 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 6149.4358974
If we subtract 156 from 170, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
39 can be fit into 140 3 times, resulting in a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 6149.43589743
If we take 117 away from 140, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 6149.43589743 with a remainder of 2.3e-08.
