Let's divide 39965289 by 814
We want to figure out the number of times 39965289 can be divided by 814.

On to step 1:
814 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 814

Going ahead to step 2:
The number 814 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 814

Going ahead to step 3:
If we divide 399 by 814, we get 0 and a remainder of 399.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Grab the next digit (6) from the dividend, add it to 399, then carry on: 3996 / 814

On to step 4:
3996 divided by 814 is 4 with a remainder of 740.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3256 away from 3996, we end up with 740.
Fetch the next digit (5) from the dividend, attach it to 740 and continue: 7405 / 814

Going ahead to step 5:
The number 814 fits into 7405 9 times, leaving a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we subtract 7326 from 7405, we get 79.
Grab the next digit (2) from the dividend, add it to 79, then carry on: 792 / 814

Moving on to step 6:
792 divided by 814 is 0 with a remainder of 792.
Record the quotient 0 as the next digit in the result. 
Result so far: 490.0
Subtracting 0 from 792 leaves us with 792.
Fetch the next digit (8) from the dividend, attach it to 792 and continue: 7928 / 814

Advancing to step 7:
814 goes into 7928 9 times with a remainder of 602.
Use 9 as the next digit of our solution. 
Result so far: 4909.0
If we take 7326 away from 7928, we end up with 602.
Bring next digit (9) of the dividend behind the 602 and repeat the process: 6029 / 814

Advancing to step 8:
If we divide 6029 by 814, we get 7 and a remainder of 331.
Use 7 as the next digit of our solution. 
Result so far: 49097.0
If we subtract 5698 from 6029, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 9:
814 can be fit into 3310 4 times, resulting in a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 49097.4
Subtract 3256 from 3310 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
When dividing 540 by 814, we get 0 with a remainder of 540.
Record the quotient 0 as the next digit in the result. 
Result so far: 49097.4
Subtract 0 from 540 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 11:
5400 divided by 814 is 6 with a remainder of 516.
The number 6 becomes the next digit in our result. 
Result so far: 49097.406
The remainder is 516 after subtracting 4884 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 12:
5160 divided by 814 is 6 with a remainder of 276.
Write down 6 as next digit of the result. 
Result so far: 49097.4066
Deduct 4884 from 5160 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The final result is 49097.4066 with a remainder of 0.00276.
