66874888 ÷ 512 
We want to figure out the number of times 66874888 can be divided by 512.

Going ahead to step 1:
The number 512 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 512

Moving on to step 2:
512 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 512

Moving on to step 3:
512 can be fit into 668 1 times, resulting in a remainder of 156.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 512 from 668, we get 156.
Bring next digit (7) of the dividend behind the 156 and repeat the process: 1567 / 512

Step 4:
1567 divided by 512 is 3 with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1536 away from 1567, we end up with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 512

On to step 5:
512 goes into 314 0 times with a remainder of 314.
Write down 0 as next digit of the result. 
Result so far: 130.0
If we take 0 away from 314, we end up with 314.
Append the next digit (8) from the dividend to 314 and continue with: 3148 / 512

Going ahead to step 6:
If we divide 3148 by 512, we get 6 and a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 1306.0
Subtracting 3072 from 3148 leaves us with 76.
Append the next digit (8) from the dividend to 76 and continue with: 768 / 512

Moving on to step 7:
512 can be fit into 768 1 times, resulting in a remainder of 256.
Use 1 as the next digit of our solution. 
Result so far: 13061.0
If we subtract 512 from 768, we get 256.
Take the next digit (8) from the dividend and append it to 256, then repeat: 2568 / 512

Going ahead to step 8:
If we divide 2568 by 512, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 130615.0
Subtracting 2560 from 2568 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
80 divided by 512 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 130615.0
The remainder is 80 after subtracting 0 from 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 10:
800 divided by 512 is 1 with a remainder of 288.
The number 1 becomes the next digit in our result. 
Result so far: 130615.01
Subtracting 512 from 800 leaves us with 288.
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 11:
2880 divided by 512 is 5 with a remainder of 320.
The number 5 becomes the next digit in our result. 
Result so far: 130615.015
Subtract 2560 from 2880 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
3200 divided by 512 is 6 with a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 130615.0156
If we subtract 3072 from 3200, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 13:
512 can be fit into 1280 2 times, resulting in a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 130615.01562
Subtracting 1024 from 1280 leaves us 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.

Going ahead to step 14:
512 can be fit into 2560 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 130615.015625
If we take 2560 away from 2560, we end up 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.

Advancing to step 15:
512 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 130615.015625
If we take 0 away from 0, we end up 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.

Going ahead to step 16:
512 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 130615.015625
Subtract 0 from 0 to 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.

The final outcome is 130615.015625, with a leftover of 0.0.
