755803 ÷ 66 
We're looking to find how many times 66 goes into 755803.

Advancing to step 1:
66 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 66

Going ahead to step 2:
The number 66 fits into 75 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 66 from 75 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 66

Let's proceed to step 3:
95 divided by 66 is 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 66 from 95 leaves us with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 66

Moving on to step 4:
When dividing 298 by 66, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Subtracting 264 from 298 leaves us with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 66

Going ahead to step 5:
The number 66 fits into 340 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 1145.0
Subtract 330 from 340 to get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 66

Let's proceed to step 6:
66 goes into 103 1 times with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 11451.0
If we subtract 66 from 103, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
66 goes into 370 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 11451.5
If we take 330 away from 370, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 66 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 11451.56
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 66, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 11451.56
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
66 can be fit into 400 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 11451.5606
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
66 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 11451.5606
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
When dividing 400 by 66, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 11451.560606
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
40 divided by 66 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11451.560606
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
400 divided by 66 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 11451.56060606
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 11451.56060606 with a balance of 4e-09.
