We look at the division of 273802 by 51 
The aim is to understand the frequency of 51 in 273802.

Going ahead to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 51

Advancing to step 2:
51 can be fit into 27 0 times, resulting in a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 51

Going ahead to step 3:
If we divide 273 by 51, we get 5 and a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 255 from 273, we get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 51

Advancing to step 4:
188 divided by 51 is 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 53.0
The remainder is 35 after subtracting 153 from 188.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 51

Step 5:
51 goes into 350 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 536.0
Deduct 306 from 350 and we're left with 44.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 51

Advancing to step 6:
The number 51 fits into 442 8 times, leaving a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 5368.0
The remainder is 34 after subtracting 408 from 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
51 goes into 340 6 times with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 5368.6
The remainder is 34 after subtracting 306 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
51 can be fit into 340 6 times, resulting in a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 5368.66
If we take 306 away from 340, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 5368.66 with a remaining 0.034.
