Let's divide 50903081 by 429
The aim is to understand the frequency of 429 in 50903081.

Advancing to step 1:
429 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 429

Going ahead to step 2:
The number 429 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 429

Moving on to step 3:
When dividing 509 by 429, we get 1 with a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 429 from 509, we get 80.
Take the next digit (0) from the dividend and append it to 80, then repeat: 800 / 429

Advancing to step 4:
When dividing 800 by 429, we get 1 with a remainder of 371.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 429 from 800 to get 371.
Include the next digit (3) from the dividend after 371, then repeat: 3713 / 429

Let's proceed to step 5:
The number 429 fits into 3713 8 times, leaving a remainder of 281.
Use 8 as the next digit of our solution. 
Result so far: 118.0
If we subtract 3432 from 3713, we get 281.
Include the next digit (0) from the dividend after 281, then repeat: 2810 / 429

Let's proceed to step 6:
When dividing 2810 by 429, we get 6 with a remainder of 236.
Put 6 as the next digit of the answer. 
Result so far: 1186.0
The remainder is 236 after subtracting 2574 from 2810.
Include the next digit (8) from the dividend after 236, then repeat: 2368 / 429

Step 7:
429 goes into 2368 5 times with a remainder of 223.
Put 5 as the next digit of the answer. 
Result so far: 11865.0
Subtract 2145 from 2368 to get 223.
Bring next digit (1) of the dividend behind the 223 and repeat the process: 2231 / 429

Let's proceed to step 8:
2231 divided by 429 is 5 with a remainder of 86.
Put 5 as the next digit of the answer. 
Result so far: 118655.0
The remainder is 86 after subtracting 2145 from 2231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
When dividing 860 by 429, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 118655.2
If we subtract 858 from 860, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
429 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 118655.2
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
The number 429 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 118655.2
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 118655.2 with a remainder of 0.02.
