76450909 divided by 512 
We're looking to find how many times 512 goes into 76450909.

Step 1:
When dividing 7 by 512, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 512

On to step 2:
If we divide 76 by 512, we get 0 and a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Take the next digit (4) from the dividend and append it to 76, then repeat: 764 / 512

Step 3:
If we divide 764 by 512, we get 1 and a remainder of 252.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 512 from 764, we get 252.
Grab the next digit (5) from the dividend, add it to 252, then carry on: 2525 / 512

On to step 4:
The number 512 fits into 2525 4 times, leaving a remainder of 477.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 2048 from 2525 and we're left with 477.
Bring next digit (0) of the dividend behind the 477 and repeat the process: 4770 / 512

On to step 5:
The number 512 fits into 4770 9 times, leaving a remainder of 162.
Write down 9 as next digit of the result. 
Result so far: 149.0
Subtract 4608 from 4770 to get 162.
Take the next digit (9) from the dividend and append it to 162, then repeat: 1629 / 512

Let's proceed to step 6:
1629 divided by 512 is 3 with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 1493.0
Subtracting 1536 from 1629 leaves us with 93.
Append the next digit (0) from the dividend to 93 and continue with: 930 / 512

Let's proceed to step 7:
512 can be fit into 930 1 times, resulting in a remainder of 418.
The number 1 becomes the next digit in our result. 
Result so far: 14931.0
If we take 512 away from 930, we end up with 418.
Include the next digit (9) from the dividend after 418, then repeat: 4189 / 512

Advancing to step 8:
4189 divided by 512 is 8 with a remainder of 93.
Write down 8 as next digit of the result. 
Result so far: 149318.0
If we subtract 4096 from 4189, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 9:
512 goes into 930 1 times with a remainder of 418.
Use 1 as the next digit of our solution. 
Result so far: 149318.1
If we take 512 away from 930, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 10:
512 can be fit into 4180 8 times, resulting in a remainder of 84.
The next digit of our result is 8. 
Result so far: 149318.18
Subtracting 4096 from 4180 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
When dividing 840 by 512, we get 1 with a remainder of 328.
The number 1 becomes the next digit in our result. 
Result so far: 149318.181
If we subtract 512 from 840, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 12:
512 can be fit into 3280 6 times, resulting in a remainder of 208.
Record the quotient 6 as the next digit in the result. 
Result so far: 149318.1816
Subtracting 3072 from 3280 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 13:
2080 divided by 512 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 149318.18164
Subtracting 2048 from 2080 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
512 can be fit into 320 0 times, resulting in a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 149318.18164
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
3200 divided by 512 is 6 with a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 149318.1816406
The remainder is 128 after subtracting 3072 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 16:
1280 divided by 512 is 2 with a remainder of 256.
Record the quotient 2 as the next digit in the result. 
Result so far: 149318.18164062
Deduct 1024 from 1280 and we're left with 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 outcome is 149318.18164062, with a leftover of 2.56e-07.
