39799729 ÷ 807 
Let's see how many times 807 fits into 39799729.

Going ahead to step 1:
807 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 807

Advancing to step 2:
807 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 807

Let's proceed to step 3:
397 divided by 807 is 0 with a remainder of 397.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 397 after subtracting 0 from 397.
Fetch the next digit (9) from the dividend, attach it to 397 and continue: 3979 / 807

Step 4:
The number 807 fits into 3979 4 times, leaving a remainder of 751.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 751 after subtracting 3228 from 3979.
Bring next digit (9) of the dividend behind the 751 and repeat the process: 7519 / 807

Advancing to step 5:
If we divide 7519 by 807, we get 9 and a remainder of 256.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we take 7263 away from 7519, we end up with 256.
Include the next digit (7) from the dividend after 256, then repeat: 2567 / 807

Moving on to step 6:
807 goes into 2567 3 times with a remainder of 146.
The number 3 becomes the next digit in our result. 
Result so far: 493.0
Deduct 2421 from 2567 and we're left with 146.
Bring next digit (2) of the dividend behind the 146 and repeat the process: 1462 / 807

Going ahead to step 7:
807 can be fit into 1462 1 times, resulting in a remainder of 655.
Use 1 as the next digit of our solution. 
Result so far: 4931.0
If we take 807 away from 1462, we end up with 655.
Bring next digit (9) of the dividend behind the 655 and repeat the process: 6559 / 807

Advancing to step 8:
The number 807 fits into 6559 8 times, leaving a remainder of 103.
Record the quotient 8 as the next digit in the result. 
Result so far: 49318.0
Deduct 6456 from 6559 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 9:
1030 divided by 807 is 1 with a remainder of 223.
Put 1 as the next digit of the answer. 
Result so far: 49318.1
If we subtract 807 from 1030, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 10:
2230 divided by 807 is 2 with a remainder of 616.
Put 2 as the next digit of the answer. 
Result so far: 49318.12
Subtracting 1614 from 2230 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 11:
807 can be fit into 6160 7 times, resulting in a remainder of 511.
Write down 7 as next digit of the result. 
Result so far: 49318.127
If we take 5649 away from 6160, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Step 12:
5110 divided by 807 is 6 with a remainder of 268.
Put 6 as the next digit of the answer. 
Result so far: 49318.1276
Deduct 4842 from 5110 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 13:
807 can be fit into 2680 3 times, resulting in a remainder of 259.
The next digit of our result is 3. 
Result so far: 49318.12763
Subtract 2421 from 2680 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 14:
2590 divided by 807 is 3 with a remainder of 169.
Put 3 as the next digit of the answer. 
Result so far: 49318.127633
The remainder is 169 after subtracting 2421 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

The quotient of the division is 49318.127633, and the remainder is 1.69e-05.
