We look at the division of 39964802 by 808 
We want to divide 39964802 by 808.

On to step 1:
3 divided by 808 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 808

Step 2:
When dividing 39 by 808, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 808

Let's proceed to step 3:
The number 808 fits into 399 0 times, leaving a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 399, we end up with 399.
Fetch the next digit (6) from the dividend, attach it to 399 and continue: 3996 / 808

Step 4:
When dividing 3996 by 808, we get 4 with a remainder of 764.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3232 away from 3996, we end up with 764.
Append the next digit (4) from the dividend to 764 and continue with: 7644 / 808

Step 5:
808 goes into 7644 9 times with a remainder of 372.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
The remainder is 372 after subtracting 7272 from 7644.
Append the next digit (8) from the dividend to 372 and continue with: 3728 / 808

Step 6:
808 can be fit into 3728 4 times, resulting in a remainder of 496.
Record the quotient 4 as the next digit in the result. 
Result so far: 494.0
If we take 3232 away from 3728, we end up with 496.
Include the next digit (0) from the dividend after 496, then repeat: 4960 / 808

Step 7:
If we divide 4960 by 808, we get 6 and a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 4946.0
If we take 4848 away from 4960, we end up with 112.
Fetch the next digit (2) from the dividend, attach it to 112 and continue: 1122 / 808

Advancing to step 8:
808 can be fit into 1122 1 times, resulting in a remainder of 314.
The next digit of our result is 1. 
Result so far: 49461.0
If we subtract 808 from 1122, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 9:
808 goes into 3140 3 times with a remainder of 716.
The next digit of our result is 3. 
Result so far: 49461.3
Subtract 2424 from 3140 to get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

On to step 10:
808 goes into 7160 8 times with a remainder of 696.
Record the quotient 8 as the next digit in the result. 
Result so far: 49461.38
Subtracting 6464 from 7160 leaves us 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.

Going ahead to step 11:
If we divide 6960 by 808, we get 8 and a remainder of 496.
Put 8 as the next digit of the answer. 
Result so far: 49461.388
If we take 6464 away from 6960, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

The final result is 49461.388 with a remainder of 0.0496.
