Let's divide 817917 by 51
Let's see how many times 51 fits into 817917.

Step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 51

On to step 2:
If we divide 81 by 51, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 51 from 81, we get 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 51

Moving on to step 3:
The number 51 fits into 307 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 306 from 307 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 51

Step 4:
When dividing 19 by 51, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
Deduct 0 from 19 and we're left with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 51

Moving on to step 5:
51 goes into 191 3 times with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 1603.0
Deduct 153 from 191 and we're left with 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 51

Let's proceed to step 6:
51 can be fit into 387 7 times, resulting in a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 16037.0
If we take 357 away from 387, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
51 goes into 300 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 16037.5
If we subtract 255 from 300, we 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.

Advancing to step 8:
450 divided by 51 is 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 16037.58
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.

Going ahead to step 9:
The number 51 fits into 420 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 16037.588
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 16037.588, with a leftover of 0.0012.
