We look at the division of 432159 by 29 
The aim is to understand the frequency of 29 in 432159.

Step 1:
When dividing 4 by 29, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 29

Advancing to step 2:
29 can be fit into 43 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 29 from 43, we get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 29

Advancing to step 3:
29 goes into 142 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 116 from 142 to get 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 29

Moving on to step 4:
The number 29 fits into 261 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
If we take 261 away from 261, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 29

Advancing to step 5:
29 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 1490.0
Subtract 0 from 5 to get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 29

Advancing to step 6:
59 divided by 29 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 14902.0
If we take 58 away from 59, we end up 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.

Going ahead to step 7:
29 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 14902.0
Subtracting 0 from 10 leaves us 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.

Moving on to step 8:
The number 29 fits into 100 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 14902.03
If we subtract 87 from 100, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
If we divide 130 by 29, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 14902.034
The remainder is 14 after subtracting 116 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
The number 29 fits into 140 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 14902.0344
Deduct 116 from 140 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 14902.0344, and the remainder is 0.00024.
