519756 divided by 39 
The aim is to understand the frequency of 39 in 519756.

On to step 1:
39 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 39

On to step 2:
51 divided by 39 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 39 from 51 to get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 39

On to step 3:
39 can be fit into 129 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 117 from 129 to get 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 39

Moving on to step 4:
If we divide 127 by 39, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 133.0
If we take 117 away from 127, we end up with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 39

On to step 5:
39 goes into 105 2 times with a remainder of 27.
The next digit of our result is 2. 
Result so far: 1332.0
Subtract 78 from 105 to get 27.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 39

Moving on to step 6:
39 can be fit into 276 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 13327.0
Deduct 273 from 276 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.

Step 7:
39 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 13327.0
If we take 0 away from 30, 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 8:
300 divided by 39 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 13327.07
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.

On to step 9:
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: 13327.076
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 10:
360 divided by 39 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 13327.0769
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 11:
When dividing 90 by 39, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 13327.07692
Deduct 78 from 90 and we're left 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.

Moving on to step 12:
39 goes into 120 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 13327.076923
Subtract 117 from 120 to 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.

Let's proceed to step 13:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 13327.076923
If we subtract 0 from 30, we 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.

Step 14:
39 can be fit into 300 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 13327.07692307
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 13327.07692307 with a balance of 2.7e-08.
