We divide 830478 by 51
The aim is to understand the frequency of 51 in 830478.

Going ahead to step 1:
51 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 51

On to step 2:
83 divided by 51 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 51 from 83 and we're left with 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 51

On to step 3:
51 goes into 320 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 306 from 320 to get 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 51

Step 4:
144 divided by 51 is 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 162.0
If we subtract 102 from 144, we get 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 51

Let's proceed to step 5:
The number 51 fits into 427 8 times, leaving a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 1628.0
Deduct 408 from 427 and we're left with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 51

Advancing to step 6:
The number 51 fits into 198 3 times, leaving a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 16283.0
If we take 153 away from 198, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing 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: 16283.8
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.

Moving on to step 8:
When dividing 420 by 51, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 16283.88
Deduct 408 from 420 and we're left 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 16283.88, with a leftover of 0.012.
