We're dividing 39396043 by 505 
We want to figure out the number of times 39396043 can be divided by 505.

Going ahead to step 1:
505 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 505

Let's proceed to step 2:
The number 505 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 505

Going ahead to step 3:
If we divide 393 by 505, we get 0 and a remainder of 393.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 393, we get 393.
Include the next digit (9) from the dividend after 393, then repeat: 3939 / 505

Advancing to step 4:
The number 505 fits into 3939 7 times, leaving a remainder of 404.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 3535 from 3939 leaves us with 404.
Include the next digit (6) from the dividend after 404, then repeat: 4046 / 505

On to step 5:
505 can be fit into 4046 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtracting 4040 from 4046 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 505

Step 6:
When dividing 60 by 505, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 780.0
The remainder is 60 after subtracting 0 from 60.
Take the next digit (4) from the dividend and append it to 60, then repeat: 604 / 505

Moving on to step 7:
505 can be fit into 604 1 times, resulting in a remainder of 99.
The next digit of our result is 1. 
Result so far: 7801.0
Subtract 505 from 604 to get 99.
Append the next digit (3) from the dividend to 99 and continue with: 993 / 505

On to step 8:
505 goes into 993 1 times with a remainder of 488.
The next digit of our result is 1. 
Result so far: 78011.0
Subtracting 505 from 993 leaves us 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 9:
If we divide 4880 by 505, we get 9 and a remainder of 335.
The next digit of our result is 9. 
Result so far: 78011.9
Subtracting 4545 from 4880 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 10:
505 goes into 3350 6 times with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 78011.96
Deduct 3030 from 3350 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 11:
If we divide 3200 by 505, we get 6 and a remainder of 170.
Record the quotient 6 as the next digit in the result. 
Result so far: 78011.966
If we take 3030 away from 3200, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 78011.966, with a leftover of 0.017.
