We divide 78491777 by 75
We want to figure out the number of times 78491777 can be divided by 75.

Moving on to step 1:
7 divided by 75 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 75

Step 2:
The number 75 fits into 78 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 75 away from 78, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 75

Advancing to step 3:
75 goes into 34 0 times with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 34, we get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 75

Moving on to step 4:
The number 75 fits into 349 4 times, leaving a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
If we take 300 away from 349, we end up with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 75

On to step 5:
If we divide 491 by 75, we get 6 and a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 1046.0
Deduct 450 from 491 and we're left with 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 75

Moving on to step 6:
417 divided by 75 is 5 with a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 10465.0
Subtract 375 from 417 to get 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 75

Step 7:
427 divided by 75 is 5 with a remainder of 52.
Use 5 as the next digit of our solution. 
Result so far: 104655.0
Subtract 375 from 427 to get 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 75

Step 8:
The number 75 fits into 527 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 1046557.0
If we take 525 away from 527, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
If we divide 20 by 75, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1046557.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
The number 75 fits into 200 2 times, leaving a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 1046557.02
Subtract 150 from 200 to 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.

Moving on to step 11:
When dividing 500 by 75, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 1046557.026
If we subtract 450 from 500, 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.

Step 12:
500 divided by 75 is 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 1046557.0266
Subtracting 450 from 500 leaves us with 50.
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 1046557.0266 with a remainder of 0.0005.
