Let's divide 755721 by 66
Let's see how many times 66 fits into 755721.

Step 1:
66 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 66

Moving on to step 2:
The number 66 fits into 75 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 9 after subtracting 66 from 75.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 66

On to step 3:
66 goes into 95 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 66 from 95 to get 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 66

Going ahead to step 4:
The number 66 fits into 297 4 times, leaving a remainder of 33.
The next digit of our result is 4. 
Result so far: 114.0
Subtracting 264 from 297 leaves us with 33.
Take the next digit (2) from the dividend and append it to 33, then repeat: 332 / 66

Going ahead to step 5:
The number 66 fits into 332 5 times, leaving a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 1145.0
If we subtract 330 from 332, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 66

Let's proceed to step 6:
When dividing 21 by 66, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 11450.0
Deduct 0 from 21 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
The number 66 fits into 210 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 11450.3
Subtract 198 from 210 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 66, we get 1 and a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 11450.31
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
When dividing 540 by 66, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 11450.318
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
66 goes into 120 1 times with a remainder of 54.
The next digit of our result is 1. 
Result so far: 11450.3181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
66 goes into 540 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 11450.31818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
66 can be fit into 120 1 times, resulting in a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 11450.318181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 11450.3181818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
66 goes into 120 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 11450.31818181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 11450.31818181, and the remainder is 5.4e-08.
