519130 ÷ 39 
The aim is to understand the frequency of 39 in 519130.

Let's proceed to step 1:
39 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 39

Moving on to step 2:
39 can be fit into 51 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 12 after subtracting 39 from 51.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 39

Moving on to step 3:
When dividing 129 by 39, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 117 from 129 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 39

Advancing to step 4:
121 divided by 39 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 133.0
Subtracting 117 from 121 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 39

Going ahead to step 5:
The number 39 fits into 43 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1331.0
Subtracting 39 from 43 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 39

Step 6:
39 can be fit into 40 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 13311.0
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 39 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 13311.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
39 can be fit into 100 2 times, resulting in a remainder of 22.
The next digit of our result is 2. 
Result so far: 13311.02
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
39 goes into 220 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 13311.025
Subtracting 195 from 220 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
When dividing 250 by 39, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 13311.0256
The remainder is 16 after subtracting 234 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
160 divided by 39 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 13311.02564
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
39 goes into 40 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 13311.025641
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
The number 39 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 13311.025641
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
When dividing 100 by 39, we get 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 13311.02564102
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 13311.02564102, and the remainder is 2.2e-08.
