66605648 divided by 512 
Let's see how many times 512 fits into 66605648.

Going ahead to step 1:
512 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 512

On to step 2:
If we divide 66 by 512, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 512

Let's proceed to step 3:
512 can be fit into 666 1 times, resulting in a remainder of 154.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 154 after subtracting 512 from 666.
Take the next digit (0) from the dividend and append it to 154, then repeat: 1540 / 512

Moving on to step 4:
512 goes into 1540 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1536 away from 1540, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 512

Advancing to step 5:
512 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 130.0
Subtract 0 from 45 to get 45.
Grab the next digit (6) from the dividend, add it to 45, then carry on: 456 / 512

Let's proceed to step 6:
The number 512 fits into 456 0 times, leaving a remainder of 456.
The next digit of our result is 0. 
Result so far: 1300.0
The remainder is 456 after subtracting 0 from 456.
Bring next digit (4) of the dividend behind the 456 and repeat the process: 4564 / 512

Let's proceed to step 7:
512 goes into 4564 8 times with a remainder of 468.
Record the quotient 8 as the next digit in the result. 
Result so far: 13008.0
If we take 4096 away from 4564, we end up with 468.
Fetch the next digit (8) from the dividend, attach it to 468 and continue: 4688 / 512

Let's proceed to step 8:
When dividing 4688 by 512, we get 9 with a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 130089.0
If we subtract 4608 from 4688, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
800 divided by 512 is 1 with a remainder of 288.
Write down 1 as next digit of the result. 
Result so far: 130089.1
The remainder is 288 after subtracting 512 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 10:
When dividing 2880 by 512, we get 5 with a remainder of 320.
Record the quotient 5 as the next digit in the result. 
Result so far: 130089.15
If we take 2560 away from 2880, we end up 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:
512 can be fit into 3200 6 times, resulting in a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 130089.156
Subtracting 3072 from 3200 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 12:
When dividing 1280 by 512, we get 2 with a remainder of 256.
Put 2 as the next digit of the answer. 
Result so far: 130089.1562
The remainder is 256 after subtracting 1024 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 13:
2560 divided by 512 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 130089.15625
If we subtract 2560 from 2560, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
0 divided by 512 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 130089.15625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 15:
512 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 130089.15625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 130089.15625 with a remainder of 0.0.
