571359 ÷ 39 
The aim is to understand the frequency of 39 in 571359.

On to step 1:
If we divide 5 by 39, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 39

Let's proceed to step 2:
57 divided by 39 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
If we take 39 away from 57, we end up with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 39

Going ahead to step 3:
39 can be fit into 181 4 times, resulting in a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 156 from 181 to get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 39

Step 4:
When dividing 253 by 39, we get 6 with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 146.0
Deduct 234 from 253 and we're left with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 39

Moving on to step 5:
39 can be fit into 195 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1465.0
Subtract 195 from 195 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 39

Step 6:
If we divide 9 by 39, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 14650.0
If we take 0 away from 9, we end up 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 next digit of our result is 2. 
Result so far: 14650.2
Subtracting 78 from 90 leaves us 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.

Step 8:
39 goes into 120 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 14650.23
If we take 117 away from 120, we end up 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 9:
30 divided by 39 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 14650.23
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.

On to step 10:
39 can be fit into 300 7 times, resulting in a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 14650.2307
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
If we divide 270 by 39, we get 6 and a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 14650.23076
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.

Let's proceed to step 12:
39 can be fit into 360 9 times, resulting in a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 14650.230769
If we take 351 away from 360, we end up 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.

On to step 13:
The number 39 fits into 90 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 14650.2307692
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
If we divide 120 by 39, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 14650.23076923
Subtracting 117 from 120 leaves us 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.

In conclusion, the division gives 14650.23076923 with a balance of 3e-09.
