We look at the division of 157431 by 29 
The aim is to understand the frequency of 29 in 157431.

Step 1:
When dividing 1 by 29, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 29

Advancing to step 2:
29 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 29

Advancing to step 3:
157 divided by 29 is 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 145 from 157 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 29

Moving on to step 4:
29 can be fit into 124 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 54.0
Deduct 116 from 124 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 29

Advancing to step 5:
83 divided by 29 is 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 542.0
Subtracting 58 from 83 leaves us with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 29

Going ahead to step 6:
If we divide 251 by 29, we get 8 and a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 5428.0
The remainder is 19 after subtracting 232 from 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
If we divide 190 by 29, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 5428.6
The remainder is 16 after subtracting 174 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
The number 29 fits into 160 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 5428.65
Subtract 145 from 160 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
When dividing 150 by 29, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5428.655
If we take 145 away from 150, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 5428.655 with a remainder of 0.0005.
