Let's divide 342183 by 39
The aim is to understand the frequency of 39 in 342183.

Let's proceed to step 1:
39 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 39

Step 2:
39 goes into 34 0 times with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 39

Moving on to step 3:
If we divide 342 by 39, we get 8 and a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 312 from 342, we get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 39

On to step 4:
39 can be fit into 301 7 times, resulting in a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we take 273 away from 301, we end up with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 39

On to step 5:
39 can be fit into 288 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 877.0
Subtract 273 from 288 to get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 39

Going ahead to step 6:
If we divide 153 by 39, we get 3 and a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 8773.0
If we subtract 117 from 153, we 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.

Moving on to step 7:
39 goes into 360 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 8773.9
The remainder is 9 after subtracting 351 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
39 can be fit into 90 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 8773.92
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.

Moving on to step 9:
The number 39 fits into 120 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 8773.923
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.

On to step 10:
30 divided by 39 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 8773.923
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.

Going ahead to step 11:
The number 39 fits into 300 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 8773.92307
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.

Let's proceed to step 12:
39 can be fit into 270 6 times, resulting in a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 8773.923076
Deduct 234 from 270 and we're left 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.

Let's proceed to step 13:
The number 39 fits into 360 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 8773.9230769
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.

Step 14:
39 can be fit into 90 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 8773.92307692
Subtract 78 from 90 to 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.

The final outcome is 8773.92307692, with a leftover of 1.2e-08.
