75250840 divided by 660 
Our goal is to divide 75250840 by 660.

Step 1:
7 divided by 660 is 0 with 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.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 660

Advancing to step 2:
660 can be fit into 75 0 times, resulting in a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Include the next digit (2) from the dividend after 75, then repeat: 752 / 660

On to step 3:
The number 660 fits into 752 1 times, leaving a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 660 from 752, we get 92.
Take the next digit (5) from the dividend and append it to 92, then repeat: 925 / 660

Going ahead to step 4:
The number 660 fits into 925 1 times, leaving a remainder of 265.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 660 from 925 to get 265.
Fetch the next digit (0) from the dividend, attach it to 265 and continue: 2650 / 660

Moving on to step 5:
The number 660 fits into 2650 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
If we subtract 2640 from 2650, we get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 660

Going ahead to step 6:
The number 660 fits into 108 0 times, leaving a remainder of 108.
Write down 0 as next digit of the result. 
Result so far: 1140.0
If we subtract 0 from 108, we get 108.
Append the next digit (4) from the dividend to 108 and continue with: 1084 / 660

Advancing to step 7:
If we divide 1084 by 660, we get 1 and a remainder of 424.
Write down 1 as next digit of the result. 
Result so far: 11401.0
The remainder is 424 after subtracting 660 from 1084.
Bring next digit (0) of the dividend behind the 424 and repeat the process: 4240 / 660

Advancing to step 8:
If we divide 4240 by 660, we get 6 and a remainder of 280.
The number 6 becomes the next digit in our result. 
Result so far: 114016.0
The remainder is 280 after subtracting 3960 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 9:
2800 divided by 660 is 4 with a remainder of 160.
The next digit of our result is 4. 
Result so far: 114016.4
Deduct 2640 from 2800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
1600 divided by 660 is 2 with a remainder of 280.
Put 2 as the next digit of the answer. 
Result so far: 114016.42
Subtract 1320 from 1600 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
When dividing 2800 by 660, we get 4 with a remainder of 160.
The next digit of our result is 4. 
Result so far: 114016.424
Subtract 2640 from 2800 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
The number 660 fits into 1600 2 times, leaving a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 114016.4242
If we subtract 1320 from 1600, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 13:
660 goes into 2800 4 times with a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 114016.42424
Deduct 2640 from 2800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
The number 660 fits into 1600 2 times, leaving a remainder of 280.
The next digit of our result is 2. 
Result so far: 114016.424242
Subtract 1320 from 1600 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
660 goes into 2800 4 times with a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 114016.4242424
The remainder is 160 after subtracting 2640 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 16:
660 goes into 1600 2 times with a remainder of 280.
The next digit of our result is 2. 
Result so far: 114016.42424242
If we take 1320 away from 1600, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 114016.42424242 and a remainder of 2.8e-07.
