We're dividing 66395072 by 511 
Let's see how many times 511 fits into 66395072.

Going ahead to step 1:
6 divided by 511 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 511

Moving on to step 2:
511 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 subtract 0 from 66, we get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 511

Going ahead to step 3:
If we divide 663 by 511, we get 1 and a remainder of 152.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 511 from 663 leaves us with 152.
Append the next digit (9) from the dividend to 152 and continue with: 1529 / 511

Let's proceed to step 4:
When dividing 1529 by 511, we get 2 with a remainder of 507.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1022 away from 1529, we end up with 507.
Grab the next digit (5) from the dividend, add it to 507, then carry on: 5075 / 511

On to step 5:
511 can be fit into 5075 9 times, resulting in a remainder of 476.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtract 4599 from 5075 to get 476.
Take the next digit (0) from the dividend and append it to 476, then repeat: 4760 / 511

Moving on to step 6:
4760 divided by 511 is 9 with a remainder of 161.
The next digit of our result is 9. 
Result so far: 1299.0
The remainder is 161 after subtracting 4599 from 4760.
Fetch the next digit (7) from the dividend, attach it to 161 and continue: 1617 / 511

Advancing to step 7:
The number 511 fits into 1617 3 times, leaving a remainder of 84.
The number 3 becomes the next digit in our result. 
Result so far: 12993.0
Deduct 1533 from 1617 and we're left with 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 511

Advancing to step 8:
The number 511 fits into 842 1 times, leaving a remainder of 331.
Write down 1 as next digit of the result. 
Result so far: 129931.0
If we take 511 away from 842, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 9:
511 can be fit into 3310 6 times, resulting in a remainder of 244.
Use 6 as the next digit of our solution. 
Result so far: 129931.6
Subtract 3066 from 3310 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 10:
2440 divided by 511 is 4 with a remainder of 396.
Put 4 as the next digit of the answer. 
Result so far: 129931.64
Deduct 2044 from 2440 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 11:
511 can be fit into 3960 7 times, resulting in a remainder of 383.
Record the quotient 7 as the next digit in the result. 
Result so far: 129931.647
Deduct 3577 from 3960 and we're left with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

On to step 12:
511 goes into 3830 7 times with a remainder of 253.
Record the quotient 7 as the next digit in the result. 
Result so far: 129931.6477
If we take 3577 away from 3830, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Our division results in 129931.6477 with a remaining 0.00253.
