249570 divided by 39 
The aim is to understand the frequency of 39 in 249570.

Going ahead to step 1:
39 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 39

Advancing to step 2:
39 can be fit into 24 0 times, resulting in a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 39

Let's proceed to step 3:
249 divided by 39 is 6 with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 234 from 249 and we're left with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 39

Let's proceed to step 4:
39 can be fit into 155 3 times, resulting in a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 117 from 155 to get 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 39

Going ahead to step 5:
If we divide 387 by 39, we get 9 and a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 639.0
Subtracting 351 from 387 leaves us with 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 39

On to step 6:
The number 39 fits into 360 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 6399.0
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.

Moving on to step 7:
If we divide 90 by 39, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 6399.2
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
When dividing 120 by 39, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 6399.23
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
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: 6399.23
Subtracting 0 from 30 leaves us 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.

Going ahead to step 10:
39 can be fit into 300 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 6399.2307
The remainder is 27 after subtracting 273 from 300.
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 11:
The number 39 fits into 270 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 6399.23076
Subtract 234 from 270 to get 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 12:
39 goes into 360 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 6399.230769
Subtract 351 from 360 to 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.

Going ahead to step 13:
39 goes into 90 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 6399.2307692
If we take 78 away from 90, we end up 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.

On to step 14:
When dividing 120 by 39, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 6399.23076923
Deduct 117 from 120 and we're left 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.

The final outcome is 6399.23076923, with a leftover of 3e-09.
