We look at the division of 25214651 by 793 
The aim is to understand the frequency of 793 in 25214651.

Going ahead to step 1:
The number 793 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 793

Advancing to step 2:
The number 793 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 793

Going ahead to step 3:
793 goes into 252 0 times with a remainder of 252.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 252, we get 252.
Include the next digit (1) from the dividend after 252, then repeat: 2521 / 793

Going ahead to step 4:
The number 793 fits into 2521 3 times, leaving a remainder of 142.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 142 after subtracting 2379 from 2521.
Include the next digit (4) from the dividend after 142, then repeat: 1424 / 793

On to step 5:
If we divide 1424 by 793, we get 1 and a remainder of 631.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 793 from 1424, we get 631.
Fetch the next digit (6) from the dividend, attach it to 631 and continue: 6316 / 793

On to step 6:
793 can be fit into 6316 7 times, resulting in a remainder of 765.
The number 7 becomes the next digit in our result. 
Result so far: 317.0
The remainder is 765 after subtracting 5551 from 6316.
Fetch the next digit (5) from the dividend, attach it to 765 and continue: 7655 / 793

Advancing to step 7:
The number 793 fits into 7655 9 times, leaving a remainder of 518.
Put 9 as the next digit of the answer. 
Result so far: 3179.0
Subtracting 7137 from 7655 leaves us with 518.
Append the next digit (1) from the dividend to 518 and continue with: 5181 / 793

Advancing to step 8:
793 can be fit into 5181 6 times, resulting in a remainder of 423.
The next digit of our result is 6. 
Result so far: 31796.0
Subtract 4758 from 5181 to get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Going ahead to step 9:
793 can be fit into 4230 5 times, resulting in a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 31796.5
If we subtract 3965 from 4230, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 10:
The number 793 fits into 2650 3 times, leaving a remainder of 271.
Write down 3 as next digit of the result. 
Result so far: 31796.53
Subtracting 2379 from 2650 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 11:
793 can be fit into 2710 3 times, resulting in a remainder of 331.
Record the quotient 3 as the next digit in the result. 
Result so far: 31796.533
Subtract 2379 from 2710 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

The final result is 31796.533 with a remainder of 0.0331.
