128928 ÷ 51 
The aim is to understand the frequency of 51 in 128928.

On to step 1:
The number 51 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 51

Step 2:
The number 51 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 (8) from the dividend and append it to 12, then repeat: 128 / 51

Going ahead to step 3:
51 goes into 128 2 times with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 102 away from 128, we end up with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 51

On to step 4:
269 divided by 51 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 255 from 269 leaves us with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 51

Moving on to step 5:
The number 51 fits into 142 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 252.0
The remainder is 40 after subtracting 102 from 142.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 51

Step 6:
When dividing 408 by 51, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 2528.0
If we subtract 408 from 408, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
If we divide 0 by 51, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2528.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
51 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2528.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 2528.0 with a remaining 0.0.
