We divide 264503 by 51
The aim is to understand the frequency of 51 in 264503.

Let's proceed to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 51

On to step 2:
51 can be fit into 26 0 times, resulting in a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 51

Moving on to step 3:
264 divided by 51 is 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 255 from 264, we get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 51

Advancing to step 4:
The number 51 fits into 95 1 times, leaving a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 51 from 95 and we're left with 44.
Grab the next digit (0) from the dividend, add it to 44, then carry on: 440 / 51

Let's proceed to step 5:
440 divided by 51 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 518.0
If we subtract 408 from 440, we get 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 51

Advancing to step 6:
If we divide 323 by 51, we get 6 and a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 5186.0
The remainder is 17 after subtracting 306 from 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
51 can be fit into 170 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 5186.3
If we take 153 away from 170, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
51 can be fit into 170 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 5186.33
Subtracting 153 from 170 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 5186.33 with a remainder of 0.017.
