235969 ÷ 29 
The aim is to understand the frequency of 29 in 235969.

Advancing to step 1:
If we divide 2 by 29, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 29

On to step 2:
The number 29 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 29

Advancing to step 3:
235 divided by 29 is 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 232 from 235 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 29

Advancing to step 4:
39 divided by 29 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtract 29 from 39 to get 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 29

Going ahead to step 5:
If we divide 106 by 29, we get 3 and a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 813.0
If we subtract 87 from 106, we get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 29

On to step 6:
The number 29 fits into 199 6 times, leaving a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 8136.0
If we subtract 174 from 199, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
If we divide 250 by 29, we get 8 and a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 8136.8
Subtract 232 from 250 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
If we divide 180 by 29, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 8136.86
If we take 174 away from 180, we end up 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.

On to step 9:
29 goes into 60 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 8136.862
If we take 58 away from 60, 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 10:
29 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8136.862
Subtracting 0 from 20 leaves us 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 11:
If we divide 200 by 29, we get 6 and a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 8136.86206
If we subtract 174 from 200, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
29 can be fit into 260 8 times, resulting in a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 8136.862068
Subtract 232 from 260 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
29 goes into 280 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 8136.8620689
If we subtract 261 from 280, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
When dividing 190 by 29, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 8136.86206896
Deduct 174 from 190 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 8136.86206896 with a remainder of 1.6e-08.
