Let's divide 12659794 by 429
The aim is to understand the frequency of 429 in 12659794.

Advancing to step 1:
If we divide 1 by 429, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 429

Let's proceed to step 2:
The number 429 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 429

Moving on to step 3:
126 divided by 429 is 0 with a remainder of 126.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 126, we end up with 126.
Fetch the next digit (5) from the dividend, attach it to 126 and continue: 1265 / 429

Going ahead to step 4:
If we divide 1265 by 429, we get 2 and a remainder of 407.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 858 from 1265, we get 407.
Include the next digit (9) from the dividend after 407, then repeat: 4079 / 429

Going ahead to step 5:
When dividing 4079 by 429, we get 9 with a remainder of 218.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 3861 from 4079 to get 218.
Include the next digit (7) from the dividend after 218, then repeat: 2187 / 429

Moving on to step 6:
2187 divided by 429 is 5 with a remainder of 42.
The next digit of our result is 5. 
Result so far: 295.0
If we take 2145 away from 2187, we end up with 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 429

Step 7:
The number 429 fits into 429 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 2951.0
If we take 429 away from 429, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 429

Going ahead to step 8:
4 divided by 429 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 29510.0
Deduct 0 from 4 and we're left 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 9:
429 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 29510.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 429 is 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 29510.0
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 29510.0 with a remainder of 0.4.
