We look at the division of 392577 by 29 
The aim is to understand the frequency of 29 in 392577.

Going ahead to step 1:
29 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 29

Step 2:
If we divide 39 by 29, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 10 after subtracting 29 from 39.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 29

Going ahead to step 3:
When dividing 102 by 29, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 15 after subtracting 87 from 102.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 29

Step 4:
The number 29 fits into 155 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 135.0
Subtract 145 from 155 to get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 29

Moving on to step 5:
If we divide 107 by 29, we get 3 and a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 1353.0
Subtracting 87 from 107 leaves us with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 29

Going ahead to step 6:
29 can be fit into 207 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 13537.0
Subtracting 203 from 207 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 29 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 13537.1
Deduct 29 from 40 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
29 can be fit into 110 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 13537.13
Deduct 87 from 110 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
29 goes into 230 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 13537.137
If we take 203 away from 230, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
When dividing 270 by 29, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 13537.1379
Subtract 261 from 270 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 11:
When dividing 90 by 29, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 13537.13793
The remainder is 3 after subtracting 87 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
30 divided by 29 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 13537.137931
Subtracting 29 from 30 leaves us 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.

Let's proceed to step 13:
29 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13537.137931
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
29 can be fit into 100 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 13537.13793103
Subtract 87 from 100 to 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.

The quotient of the division is 13537.13793103, and the remainder is 1.3e-08.
