523060 ÷ 39 
The aim is to understand the frequency of 39 in 523060.

Let's proceed to step 1:
39 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 39

On to step 2:
52 divided by 39 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 39 from 52 and we're left with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 39

Step 3:
39 goes into 133 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 117 from 133 to get 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 39

Step 4:
When dividing 160 by 39, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 134.0
If we subtract 156 from 160, we get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 39

Moving on to step 5:
46 divided by 39 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1341.0
Subtract 39 from 46 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 39

Moving on to step 6:
The number 39 fits into 70 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 13411.0
Subtract 39 from 70 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
310 divided by 39 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 13411.7
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
The number 39 fits into 370 9 times, leaving a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 13411.79
Subtracting 351 from 370 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
If we divide 190 by 39, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 13411.794
If we take 156 away from 190, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
39 goes into 340 8 times with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 13411.7948
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 13411.79487
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
39 goes into 70 1 times with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 13411.794871
Subtract 39 from 70 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 13:
310 divided by 39 is 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 13411.7948717
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 14:
39 goes into 370 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 13411.79487179
Subtracting 351 from 370 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 13411.79487179 with a balance of 1.9e-08.
