39915689 divided by 805 
Our goal is to divide 39915689 by 805.

Advancing to step 1:
3 divided by 805 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 805

Let's proceed to step 2:
805 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 805

Let's proceed to step 3:
399 divided by 805 is 0 with a remainder of 399.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Fetch the next digit (1) from the dividend, attach it to 399 and continue: 3991 / 805

Advancing to step 4:
805 can be fit into 3991 4 times, resulting in a remainder of 771.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3220 from 3991 and we're left with 771.
Fetch the next digit (5) from the dividend, attach it to 771 and continue: 7715 / 805

Going ahead to step 5:
805 can be fit into 7715 9 times, resulting in a remainder of 470.
Use 9 as the next digit of our solution. 
Result so far: 49.0
The remainder is 470 after subtracting 7245 from 7715.
Append the next digit (6) from the dividend to 470 and continue with: 4706 / 805

Advancing to step 6:
If we divide 4706 by 805, we get 5 and a remainder of 681.
Write down 5 as next digit of the result. 
Result so far: 495.0
If we subtract 4025 from 4706, we get 681.
Grab the next digit (8) from the dividend, add it to 681, then carry on: 6818 / 805

Advancing to step 7:
6818 divided by 805 is 8 with a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 4958.0
The remainder is 378 after subtracting 6440 from 6818.
Bring next digit (9) of the dividend behind the 378 and repeat the process: 3789 / 805

Let's proceed to step 8:
If we divide 3789 by 805, we get 4 and a remainder of 569.
Write down 4 as next digit of the result. 
Result so far: 49584.0
Subtract 3220 from 3789 to get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Going ahead to step 9:
If we divide 5690 by 805, we get 7 and a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 49584.7
Subtract 5635 from 5690 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
When dividing 550 by 805, we get 0 with a remainder of 550.
The next digit of our result is 0. 
Result so far: 49584.7
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 11:
805 goes into 5500 6 times with a remainder of 670.
Put 6 as the next digit of the answer. 
Result so far: 49584.706
If we take 4830 away from 5500, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 12:
When dividing 6700 by 805, we get 8 with a remainder of 260.
The number 8 becomes the next digit in our result. 
Result so far: 49584.7068
If we take 6440 away from 6700, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
When dividing 2600 by 805, we get 3 with a remainder of 185.
Record the quotient 3 as the next digit in the result. 
Result so far: 49584.70683
Subtracting 2415 from 2600 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 14:
If we divide 1850 by 805, we get 2 and a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 49584.706832
If we take 1610 away from 1850, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 15:
805 can be fit into 2400 2 times, resulting in a remainder of 790.
Write down 2 as next digit of the result. 
Result so far: 49584.7068322
If we subtract 1610 from 2400, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

In conclusion, the division gives 49584.7068322 with a balance of 7.9e-06.
