We look at the division of 388399 by 29 
The aim is to understand the frequency of 29 in 388399.

Moving on to step 1:
29 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 29

Advancing to step 2:
29 can be fit into 38 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
If we take 29 away from 38, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 29

Going ahead to step 3:
If we divide 98 by 29, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 87 away from 98, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 29

Step 4:
If we divide 113 by 29, we get 3 and a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 133.0
The remainder is 26 after subtracting 87 from 113.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 29

Advancing to step 5:
If we divide 269 by 29, we get 9 and a remainder of 8.
The next digit of our result is 9. 
Result so far: 1339.0
The remainder is 8 after subtracting 261 from 269.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 29

Advancing to step 6:
89 divided by 29 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 13393.0
Deduct 87 from 89 and we're left 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 7:
20 divided by 29 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 13393.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
If we divide 200 by 29, we get 6 and a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 13393.06
The remainder is 26 after subtracting 174 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
The number 29 fits into 260 8 times, leaving a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 13393.068
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.

Going ahead to step 10:
The number 29 fits into 280 9 times, leaving a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 13393.0689
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.

Let's proceed to step 11:
190 divided by 29 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 13393.06896
If we take 174 away from 190, we end up 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.

Going ahead to step 12:
If we divide 160 by 29, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 13393.068965
If we take 145 away from 160, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
When dividing 150 by 29, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 13393.0689655
Subtract 145 from 150 to get 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 13393.0689655 with a remainder of 5e-08.
