We're dividing 10049880 by 433 
The aim is to understand the frequency of 433 in 10049880.

Advancing to step 1:
433 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 433

On to step 2:
433 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: 0.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 433

Moving on to step 3:
When dividing 100 by 433, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 100 leaves us with 100.
Fetch the next digit (4) from the dividend, attach it to 100 and continue: 1004 / 433

Step 4:
The number 433 fits into 1004 2 times, leaving a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 866 from 1004 leaves us with 138.
Fetch the next digit (9) from the dividend, attach it to 138 and continue: 1389 / 433

On to step 5:
433 goes into 1389 3 times with a remainder of 90.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 1299 from 1389 leaves us with 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 433

On to step 6:
433 can be fit into 908 2 times, resulting in a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 232.0
If we take 866 away from 908, we end up with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 433

On to step 7:
The number 433 fits into 428 0 times, leaving a remainder of 428.
The next digit of our result is 0. 
Result so far: 2320.0
Subtracting 0 from 428 leaves us with 428.
Fetch the next digit (0) from the dividend, attach it to 428 and continue: 4280 / 433

Advancing to step 8:
The number 433 fits into 4280 9 times, leaving a remainder of 383.
Use 9 as the next digit of our solution. 
Result so far: 23209.0
If we take 3897 away from 4280, we end up with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

On to step 9:
433 can be fit into 3830 8 times, resulting in a remainder of 366.
Record the quotient 8 as the next digit in the result. 
Result so far: 23209.8
If we subtract 3464 from 3830, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 10:
433 can be fit into 3660 8 times, resulting in a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 23209.88
Subtracting 3464 from 3660 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

After the division, we end up with 23209.88 and a remainder of 0.196.
