We look at the division of 432051 by 39 
The aim is to understand the frequency of 39 in 432051.

Let's proceed to step 1:
If we divide 4 by 39, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 39

Step 2:
The number 39 fits into 43 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 4 after subtracting 39 from 43.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 39

Let's proceed to step 3:
The number 39 fits into 42 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 3 after subtracting 39 from 42.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 39

On to step 4:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
If we take 0 away from 30, we end up with 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 39

Going ahead to step 5:
If we divide 305 by 39, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 1107.0
Subtract 273 from 305 to get 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 39

Step 6:
The number 39 fits into 321 8 times, leaving a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 11078.0
Subtract 312 from 321 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.

On to step 7:
39 goes into 90 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 11078.2
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.

Moving on to step 8:
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: 11078.23
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.

Advancing to step 9:
30 divided by 39 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 11078.23
Subtract 0 from 30 to 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.

Moving on to step 10:
When dividing 300 by 39, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 11078.2307
If we subtract 273 from 300, we 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.

On to step 11:
270 divided by 39 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 11078.23076
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 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: 11078.230769
Subtracting 351 from 360 leaves us 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:
39 goes into 90 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 11078.2307692
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.

Advancing to step 14:
39 goes into 120 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 11078.23076923
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.

In conclusion, the division gives 11078.23076923 with a balance of 3e-09.
