75869343 divided by 660 
Our goal is to divide 75869343 by 660.

On to step 1:
660 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
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 660

Advancing to step 2:
75 divided by 660 is 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Fetch the next digit (8) from the dividend, attach it to 75 and continue: 758 / 660

Step 3:
The number 660 fits into 758 1 times, leaving a remainder of 98.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 660 from 758 to get 98.
Include the next digit (6) from the dividend after 98, then repeat: 986 / 660

Going ahead to step 4:
660 goes into 986 1 times with a remainder of 326.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 660 from 986 leaves us with 326.
Append the next digit (9) from the dividend to 326 and continue with: 3269 / 660

Advancing to step 5:
660 goes into 3269 4 times with a remainder of 629.
Write down 4 as next digit of the result. 
Result so far: 114.0
Deduct 2640 from 3269 and we're left with 629.
Grab the next digit (3) from the dividend, add it to 629, then carry on: 6293 / 660

Let's proceed to step 6:
6293 divided by 660 is 9 with a remainder of 353.
The next digit of our result is 9. 
Result so far: 1149.0
If we subtract 5940 from 6293, we get 353.
Take the next digit (4) from the dividend and append it to 353, then repeat: 3534 / 660

Moving on to step 7:
3534 divided by 660 is 5 with a remainder of 234.
The next digit of our result is 5. 
Result so far: 11495.0
Subtract 3300 from 3534 to get 234.
Grab the next digit (3) from the dividend, add it to 234, then carry on: 2343 / 660

On to step 8:
660 goes into 2343 3 times with a remainder of 363.
Put 3 as the next digit of the answer. 
Result so far: 114953.0
If we subtract 1980 from 2343, we get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

On to step 9:
When dividing 3630 by 660, we get 5 with a remainder of 330.
Put 5 as the next digit of the answer. 
Result so far: 114953.5
Deduct 3300 from 3630 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
660 goes into 3300 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 114953.55
If we subtract 3300 from 3300, we 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 quotient of the division is 114953.55, and the remainder is 0.0.
