We're dividing 39253411 by 766 
Let's see how many times 766 fits into 39253411.

On to step 1:
When dividing 3 by 766, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 766

Moving on to step 2:
The number 766 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 766

Moving on to step 3:
766 can be fit into 392 0 times, resulting in a remainder of 392.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 392 after subtracting 0 from 392.
Append the next digit (5) from the dividend to 392 and continue with: 3925 / 766

Going ahead to step 4:
The number 766 fits into 3925 5 times, leaving a remainder of 95.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 3830 from 3925 to get 95.
Include the next digit (3) from the dividend after 95, then repeat: 953 / 766

Let's proceed to step 5:
The number 766 fits into 953 1 times, leaving a remainder of 187.
Write down 1 as next digit of the result. 
Result so far: 51.0
The remainder is 187 after subtracting 766 from 953.
Take the next digit (4) from the dividend and append it to 187, then repeat: 1874 / 766

On to step 6:
766 goes into 1874 2 times with a remainder of 342.
The next digit of our result is 2. 
Result so far: 512.0
Subtracting 1532 from 1874 leaves us with 342.
Fetch the next digit (1) from the dividend, attach it to 342 and continue: 3421 / 766

Advancing to step 7:
If we divide 3421 by 766, we get 4 and a remainder of 357.
Write down 4 as next digit of the result. 
Result so far: 5124.0
If we take 3064 away from 3421, we end up with 357.
Take the next digit (1) from the dividend and append it to 357, then repeat: 3571 / 766

Going ahead to step 8:
When dividing 3571 by 766, we get 4 with a remainder of 507.
Record the quotient 4 as the next digit in the result. 
Result so far: 51244.0
The remainder is 507 after subtracting 3064 from 3571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Let's proceed to step 9:
If we divide 5070 by 766, we get 6 and a remainder of 474.
Put 6 as the next digit of the answer. 
Result so far: 51244.6
The remainder is 474 after subtracting 4596 from 5070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 10:
The number 766 fits into 4740 6 times, leaving a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 51244.66
Deduct 4596 from 4740 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final result is 51244.66 with a remainder of 0.144.
