We're dividing 12702449 by 75 
We want to figure out the number of times 12702449 can be divided by 75.

Step 1:
75 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 75

Going ahead to step 2:
12 divided by 75 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 75

Let's proceed to step 3:
The number 75 fits into 127 1 times, leaving a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 75 away from 127, we end up with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 75

On to step 4:
If we divide 520 by 75, we get 6 and a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 450 from 520 and we're left with 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 75

Advancing to step 5:
The number 75 fits into 702 9 times, leaving a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
If we subtract 675 from 702, we get 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 75

Moving on to step 6:
When dividing 274 by 75, we get 3 with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 1693.0
If we take 225 away from 274, we end up with 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 75

Going ahead to step 7:
494 divided by 75 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 16936.0
Subtract 450 from 494 to get 44.
Bring next digit (9) of the dividend behind the 44 and repeat the process: 449 / 75

Step 8:
75 can be fit into 449 5 times, resulting in a remainder of 74.
Put 5 as the next digit of the answer. 
Result so far: 169365.0
The remainder is 74 after subtracting 375 from 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 9:
75 goes into 740 9 times with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 169365.9
If we take 675 away from 740, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 10:
If we divide 650 by 75, we get 8 and a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 169365.98
The remainder is 50 after subtracting 600 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
75 goes into 500 6 times with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 169365.986
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
When dividing 500 by 75, we get 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 169365.9866
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 169365.9866 with a remainder of 0.0005.
