66890501 ÷ 755 
We're looking to find how many times 755 goes into 66890501.

Step 1:
6 divided by 755 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 755

Advancing to step 2:
755 goes into 66 0 times with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 755

Step 3:
If we divide 668 by 755, we get 0 and a remainder of 668.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 668, we end up with 668.
Take the next digit (9) from the dividend and append it to 668, then repeat: 6689 / 755

Going ahead to step 4:
When dividing 6689 by 755, we get 8 with a remainder of 649.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6040 away from 6689, we end up with 649.
Take the next digit (0) from the dividend and append it to 649, then repeat: 6490 / 755

On to step 5:
755 can be fit into 6490 8 times, resulting in a remainder of 450.
Put 8 as the next digit of the answer. 
Result so far: 88.0
If we subtract 6040 from 6490, we get 450.
Grab the next digit (5) from the dividend, add it to 450, then carry on: 4505 / 755

Let's proceed to step 6:
4505 divided by 755 is 5 with a remainder of 730.
Use 5 as the next digit of our solution. 
Result so far: 885.0
If we take 3775 away from 4505, we end up with 730.
Fetch the next digit (0) from the dividend, attach it to 730 and continue: 7300 / 755

Step 7:
The number 755 fits into 7300 9 times, leaving a remainder of 505.
Write down 9 as next digit of the result. 
Result so far: 8859.0
Deduct 6795 from 7300 and we're left with 505.
Bring next digit (1) of the dividend behind the 505 and repeat the process: 5051 / 755

Advancing to step 8:
If we divide 5051 by 755, we get 6 and a remainder of 521.
Write down 6 as next digit of the result. 
Result so far: 88596.0
Subtracting 4530 from 5051 leaves us with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

On to step 9:
When dividing 5210 by 755, we get 6 with a remainder of 680.
The number 6 becomes the next digit in our result. 
Result so far: 88596.6
The remainder is 680 after subtracting 4530 from 5210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 10:
755 goes into 6800 9 times with a remainder of 5.
The next digit of our result is 9. 
Result so far: 88596.69
Deduct 6795 from 6800 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
755 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 88596.69
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
The number 755 fits into 500 0 times, leaving a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 88596.69
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 88596.69 with a remaining 0.005.
