280982 divided by 51 
The aim is to understand the frequency of 51 in 280982.

Going ahead to step 1:
If we divide 2 by 51, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 51

On to step 2:
The number 51 fits into 28 0 times, leaving a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 51

On to step 3:
The number 51 fits into 280 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 255 away from 280, we end up with 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 51

On to step 4:
259 divided by 51 is 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 55.0
The remainder is 4 after subtracting 255 from 259.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 51

Step 5:
The number 51 fits into 48 0 times, leaving a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 550.0
If we subtract 0 from 48, we get 48.
Grab the next digit (2) from the dividend, add it to 48, then carry on: 482 / 51

Moving on to step 6:
When dividing 482 by 51, we get 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 5509.0
If we subtract 459 from 482, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
51 goes into 230 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 5509.4
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5509.45
Deduct 255 from 260 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
51 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 5509.45
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
When dividing 500 by 51, we get 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 5509.4509
Subtracting 459 from 500 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
51 can be fit into 410 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 5509.45098
Deduct 408 from 410 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
The number 51 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 5509.45098
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.

Advancing to step 13:
The number 51 fits into 200 3 times, leaving a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 5509.4509803
The remainder is 47 after subtracting 153 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
When dividing 470 by 51, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 5509.45098039
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 5509.45098039 with a remaining 1.1e-08.
