We divide 78480239 by 512
We want to divide 78480239 by 512.

Moving on to step 1:
512 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 512

Going ahead to step 2:
The number 512 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 512

Step 3:
512 goes into 784 1 times with a remainder of 272.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 512 from 784 to get 272.
Fetch the next digit (8) from the dividend, attach it to 272 and continue: 2728 / 512

Let's proceed to step 4:
When dividing 2728 by 512, we get 5 with a remainder of 168.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 2560 from 2728, we get 168.
Take the next digit (0) from the dividend and append it to 168, then repeat: 1680 / 512

Going ahead to step 5:
The number 512 fits into 1680 3 times, leaving a remainder of 144.
Write down 3 as next digit of the result. 
Result so far: 153.0
Subtracting 1536 from 1680 leaves us with 144.
Take the next digit (2) from the dividend and append it to 144, then repeat: 1442 / 512

On to step 6:
The number 512 fits into 1442 2 times, leaving a remainder of 418.
The number 2 becomes the next digit in our result. 
Result so far: 1532.0
Subtracting 1024 from 1442 leaves us with 418.
Fetch the next digit (3) from the dividend, attach it to 418 and continue: 4183 / 512

Moving on to step 7:
4183 divided by 512 is 8 with a remainder of 87.
Record the quotient 8 as the next digit in the result. 
Result so far: 15328.0
Subtract 4096 from 4183 to get 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 512

Advancing to step 8:
If we divide 879 by 512, we get 1 and a remainder of 367.
Record the quotient 1 as the next digit in the result. 
Result so far: 153281.0
Subtracting 512 from 879 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 9:
If we divide 3670 by 512, we get 7 and a remainder of 86.
Put 7 as the next digit of the answer. 
Result so far: 153281.7
Subtract 3584 from 3670 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 10:
If we divide 860 by 512, we get 1 and a remainder of 348.
Use 1 as the next digit of our solution. 
Result so far: 153281.71
Deduct 512 from 860 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 11:
The number 512 fits into 3480 6 times, leaving a remainder of 408.
The number 6 becomes the next digit in our result. 
Result so far: 153281.716
The remainder is 408 after subtracting 3072 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 12:
If we divide 4080 by 512, we get 7 and a remainder of 496.
Record the quotient 7 as the next digit in the result. 
Result so far: 153281.7167
If we take 3584 away from 4080, 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.

On to step 13:
If we divide 4960 by 512, we get 9 and a remainder of 352.
The number 9 becomes the next digit in our result. 
Result so far: 153281.71679
If we subtract 4608 from 4960, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 14:
The number 512 fits into 3520 6 times, leaving a remainder of 448.
Record the quotient 6 as the next digit in the result. 
Result so far: 153281.716796
If we subtract 3072 from 3520, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 15:
4480 divided by 512 is 8 with a remainder of 384.
Put 8 as the next digit of the answer. 
Result so far: 153281.7167968
If we take 4096 away from 4480, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 16:
The number 512 fits into 3840 7 times, leaving a remainder of 256.
Write down 7 as next digit of the result. 
Result so far: 153281.71679687
If we subtract 3584 from 3840, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final result is 153281.71679687 with a remainder of 2.56e-07.
