We divide 820890 by 51
Our goal is to divide 820890 by 51.

Advancing to step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 51

Advancing to step 2:
If we divide 82 by 51, we get 1 and a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 51 from 82 leaves us with 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 51

Step 3:
310 divided by 51 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 306 from 310, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 51

On to step 4:
If we divide 48 by 51, we get 0 and a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 160.0
Subtract 0 from 48 to get 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 51

Advancing to step 5:
51 can be fit into 489 9 times, resulting in a remainder of 30.
The next digit of our result is 9. 
Result so far: 1609.0
Subtracting 459 from 489 leaves us with 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 51

Let's proceed to step 6:
If we divide 300 by 51, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 16095.0
Subtracting 255 from 300 leaves us 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.

On to step 7:
If we divide 450 by 51, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 16095.8
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.

Step 8:
If we divide 420 by 51, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 16095.88
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 result is 16095.88 with a remainder of 0.012.
