We're dividing 347139 by 29 
The aim is to understand the frequency of 29 in 347139.

Advancing to step 1:
When dividing 3 by 29, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 29

Moving on to step 2:
The number 29 fits into 34 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 29 from 34 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 29

On to step 3:
57 divided by 29 is 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 29 from 57 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 29

Moving on to step 4:
When dividing 281 by 29, we get 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Subtracting 261 from 281 leaves us with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 29

On to step 5:
29 can be fit into 203 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 1197.0
The remainder is 0 after subtracting 203 from 203.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 29

Advancing to step 6:
29 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 11970.0
Subtract 0 from 9 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.

Moving on to step 7:
29 can be fit into 90 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 11970.3
If we subtract 87 from 90, 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.

Moving on to step 8:
29 can be fit into 30 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 11970.31
The remainder is 1 after subtracting 29 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
The number 29 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 11970.31
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 29, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 11970.3103
The remainder is 13 after subtracting 87 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
The number 29 fits into 130 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 11970.31034
If we take 116 away from 130, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
29 goes into 140 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 11970.310344
The remainder is 24 after subtracting 116 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 11970.310344 and a remainder of 2.4e-06.
