We divide 304311 by 51
The aim is to understand the frequency of 51 in 304311.

Moving on to step 1:
51 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 51

Going ahead to step 2:
If we divide 30 by 51, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 51

Moving on to step 3:
304 divided by 51 is 5 with a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 255 from 304 leaves us with 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 51

Let's proceed to step 4:
If we divide 493 by 51, we get 9 and a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtract 459 from 493 to get 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 51

Going ahead to step 5:
The number 51 fits into 341 6 times, leaving a remainder of 35.
The next digit of our result is 6. 
Result so far: 596.0
Subtracting 306 from 341 leaves us with 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 51

Step 6:
If we divide 351 by 51, we get 6 and a remainder of 45.
The next digit of our result is 6. 
Result so far: 5966.0
Subtract 306 from 351 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
When dividing 450 by 51, we get 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 5966.8
Subtracting 408 from 450 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
When dividing 420 by 51, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 5966.88
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 5966.88, with a leftover of 0.012.
