We look at the division of 354658 by 29 
The aim is to understand the frequency of 29 in 354658.

Going ahead 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
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 29

Advancing to step 2:
35 divided by 29 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 29 from 35 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 29

Going ahead to step 3:
The number 29 fits into 64 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 58 from 64 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 29

Let's proceed to step 4:
The number 29 fits into 66 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Subtracting 58 from 66 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 29

Moving on to step 5:
85 divided by 29 is 2 with a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 1222.0
Deduct 58 from 85 and we're left with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 29

Moving on to step 6:
When dividing 278 by 29, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 12229.0
If we take 261 away from 278, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
29 goes into 170 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12229.5
If we take 145 away from 170, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
When dividing 250 by 29, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 12229.58
Subtracting 232 from 250 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
29 can be fit into 180 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 12229.586
Deduct 174 from 180 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
The number 29 fits into 60 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 12229.5862
Subtracting 58 from 60 leaves us 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.

Moving on to step 11:
The number 29 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 12229.5862
If we take 0 away from 20, we end up 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.

Going ahead to step 12:
29 can be fit into 200 6 times, resulting in a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 12229.586206
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
29 goes into 260 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 12229.5862068
The remainder is 28 after subtracting 232 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
When dividing 280 by 29, we get 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 12229.58620689
Deduct 261 from 280 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 12229.58620689 and a remainder of 1.9e-08.
