39355913 ÷ 809 
We're looking to find how many times 809 goes into 39355913.

Step 1:
When dividing 3 by 809, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 809

Moving on to step 2:
If we divide 39 by 809, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 809

Going ahead to step 3:
809 goes into 393 0 times with a remainder of 393.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 393 to get 393.
Include the next digit (5) from the dividend after 393, then repeat: 3935 / 809

Advancing to step 4:
809 can be fit into 3935 4 times, resulting in a remainder of 699.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 699 after subtracting 3236 from 3935.
Fetch the next digit (5) from the dividend, attach it to 699 and continue: 6995 / 809

Step 5:
When dividing 6995 by 809, we get 8 with a remainder of 523.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we take 6472 away from 6995, we end up with 523.
Grab the next digit (9) from the dividend, add it to 523, then carry on: 5239 / 809

Going ahead to step 6:
5239 divided by 809 is 6 with a remainder of 385.
Record the quotient 6 as the next digit in the result. 
Result so far: 486.0
Deduct 4854 from 5239 and we're left with 385.
Fetch the next digit (1) from the dividend, attach it to 385 and continue: 3851 / 809

Moving on to step 7:
If we divide 3851 by 809, we get 4 and a remainder of 615.
Put 4 as the next digit of the answer. 
Result so far: 4864.0
Deduct 3236 from 3851 and we're left with 615.
Take the next digit (3) from the dividend and append it to 615, then repeat: 6153 / 809

On to step 8:
809 can be fit into 6153 7 times, resulting in a remainder of 490.
Put 7 as the next digit of the answer. 
Result so far: 48647.0
Subtracting 5663 from 6153 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 9:
809 goes into 4900 6 times with a remainder of 46.
The next digit of our result is 6. 
Result so far: 48647.6
Subtract 4854 from 4900 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
If we divide 460 by 809, we get 0 and a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 48647.6
The remainder is 460 after subtracting 0 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 11:
4600 divided by 809 is 5 with a remainder of 555.
The number 5 becomes the next digit in our result. 
Result so far: 48647.605
Deduct 4045 from 4600 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Step 12:
The number 809 fits into 5550 6 times, leaving a remainder of 696.
The number 6 becomes the next digit in our result. 
Result so far: 48647.6056
If we take 4854 away from 5550, we end up with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Let's proceed to step 13:
6960 divided by 809 is 8 with a remainder of 488.
The next digit of our result is 8. 
Result so far: 48647.60568
If we take 6472 away from 6960, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 14:
809 goes into 4880 6 times with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 48647.605686
If we subtract 4854 from 4880, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 15:
The number 809 fits into 260 0 times, leaving a remainder of 260.
The next digit of our result is 0. 
Result so far: 48647.605686
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 16:
If we divide 2600 by 809, we get 3 and a remainder of 173.
The number 3 becomes the next digit in our result. 
Result so far: 48647.60568603
The remainder is 173 after subtracting 2427 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Our division results in 48647.60568603 with a remaining 1.73e-07.
