84375 divided by 51 
We're looking to find how many times 51 goes into 84375.

Step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 51

Moving on to step 2:
If we divide 84 by 51, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 51 from 84 to get 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 51

On to step 3:
51 can be fit into 333 6 times, resulting in a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 306 from 333, we get 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 51

Advancing to step 4:
277 divided by 51 is 5 with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
If we subtract 255 from 277, we get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 51

Advancing to step 5:
If we divide 225 by 51, we get 4 and a remainder of 21.
The next digit of our result is 4. 
Result so far: 1654.0
If we take 204 away from 225, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 6:
51 goes into 210 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 1654.4
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
If we divide 60 by 51, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1654.41
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
51 goes into 90 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1654.411
Subtracting 51 from 90 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 1654.411 with a balance of 0.0039.
