We divide 51806857 by 805
Our goal is to divide 51806857 by 805.

Advancing to step 1:
If we divide 5 by 805, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 805

Advancing to step 2:
805 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 805

On to step 3:
805 can be fit into 518 0 times, resulting in a remainder of 518.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 518 and we're left with 518.
Fetch the next digit (0) from the dividend, attach it to 518 and continue: 5180 / 805

Step 4:
When dividing 5180 by 805, we get 6 with a remainder of 350.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 4830 away from 5180, we end up with 350.
Append the next digit (6) from the dividend to 350 and continue with: 3506 / 805

On to step 5:
805 can be fit into 3506 4 times, resulting in a remainder of 286.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 3220 from 3506 leaves us with 286.
Include the next digit (8) from the dividend after 286, then repeat: 2868 / 805

Moving on to step 6:
805 goes into 2868 3 times with a remainder of 453.
The next digit of our result is 3. 
Result so far: 643.0
Subtracting 2415 from 2868 leaves us with 453.
Bring next digit (5) of the dividend behind the 453 and repeat the process: 4535 / 805

Let's proceed to step 7:
If we divide 4535 by 805, we get 5 and a remainder of 510.
Put 5 as the next digit of the answer. 
Result so far: 6435.0
If we take 4025 away from 4535, we end up with 510.
Include the next digit (7) from the dividend after 510, then repeat: 5107 / 805

Step 8:
5107 divided by 805 is 6 with a remainder of 277.
Record the quotient 6 as the next digit in the result. 
Result so far: 64356.0
If we take 4830 away from 5107, we end up with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Going ahead to step 9:
805 goes into 2770 3 times with a remainder of 355.
Put 3 as the next digit of the answer. 
Result so far: 64356.3
Deduct 2415 from 2770 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 10:
The number 805 fits into 3550 4 times, leaving a remainder of 330.
Use 4 as the next digit of our solution. 
Result so far: 64356.34
Subtract 3220 from 3550 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 11:
3300 divided by 805 is 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 64356.344
Subtracting 3220 from 3300 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 64356.344, with a leftover of 0.008.
