818886 ÷ 51 
We want to divide 818886 by 51.

Going ahead to step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 51

Step 2:
The number 51 fits into 81 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 81 to get 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 51

Going ahead to step 3:
If we divide 308 by 51, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 306 from 308 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 51

Moving on to step 4:
When dividing 28 by 51, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 51

Advancing to step 5:
288 divided by 51 is 5 with a remainder of 33.
The next digit of our result is 5. 
Result so far: 1605.0
The remainder is 33 after subtracting 255 from 288.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 51

Let's proceed to step 6:
The number 51 fits into 336 6 times, leaving a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 16056.0
Deduct 306 from 336 and we're left 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.

Step 7:
If we divide 300 by 51, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 16056.5
If we take 255 away from 300, 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.

Step 8:
51 goes into 450 8 times with a remainder of 42.
The next digit of our result is 8. 
Result so far: 16056.58
If we subtract 408 from 450, we get 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 9:
The number 51 fits into 420 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 16056.588
The remainder is 12 after subtracting 408 from 420.
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 16056.588, with a leftover of 0.0012.
