We're dividing 134243 by 39 
The aim is to understand the frequency of 39 in 134243.

Moving on to step 1:
39 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 39

Step 2:
When dividing 13 by 39, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 39

On to step 3:
If we divide 134 by 39, we get 3 and a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 117 from 134, we get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 39

On to step 4:
If we divide 172 by 39, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 156 from 172, we get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 39

Let's proceed to step 5:
164 divided by 39 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 344.0
Deduct 156 from 164 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 39

Moving on to step 6:
39 goes into 83 2 times with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 3442.0
Deduct 78 from 83 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 39 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 3442.1
If we subtract 39 from 50, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
If we divide 110 by 39, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 3442.12
Subtracting 78 from 110 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
39 can be fit into 320 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 3442.128
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
80 divided by 39 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 3442.1282
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
39 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3442.1282
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
39 can be fit into 200 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 3442.128205
If we take 195 away from 200, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
The number 39 fits into 50 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 3442.1282051
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
The number 39 fits into 110 2 times, leaving a remainder of 32.
The next digit of our result is 2. 
Result so far: 3442.12820512
If we subtract 78 from 110, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 3442.12820512 with a balance of 3.2e-08.
