We're dividing 129711 by 34 
The aim is to understand the frequency of 34 in 129711.

Step 1:
1 divided by 34 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 34

Let's proceed to step 2:
If we divide 12 by 34, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 34

Step 3:
The number 34 fits into 129 3 times, leaving a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 102 from 129 and we're left with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 34

Step 4:
34 goes into 277 8 times with a remainder of 5.
The next digit of our result is 8. 
Result so far: 38.0
If we take 272 away from 277, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 34

Step 5:
34 can be fit into 51 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 381.0
Subtract 34 from 51 to get 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 34

Moving on to step 6:
If we divide 171 by 34, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 3815.0
Subtracting 170 from 171 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 34, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3815.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
34 can be fit into 100 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 3815.02
The remainder is 32 after subtracting 68 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
If we divide 320 by 34, we get 9 and a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 3815.029
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
34 can be fit into 140 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 3815.0294
Deduct 136 from 140 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
34 can be fit into 40 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 3815.02941
The remainder is 6 after subtracting 34 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
The number 34 fits into 60 1 times, leaving a remainder of 26.
The next digit of our result is 1. 
Result so far: 3815.029411
The remainder is 26 after subtracting 34 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 3815.029411 with a remaining 2.6e-06.
