78505 ÷ 75 
We're looking to find how many times 75 goes into 78505.

Going ahead to step 1:
If we divide 7 by 75, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 75

On to step 2:
When dividing 78 by 75, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 3 after subtracting 75 from 78.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 75

On to step 3:
75 can be fit into 35 0 times, resulting in a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 35 to get 35.
Append the next digit (0) from the dividend to 35 and continue with: 350 / 75

Going ahead to step 4:
When dividing 350 by 75, we get 4 with a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtracting 300 from 350 leaves us with 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 75

Going ahead to step 5:
If we divide 505 by 75, we get 6 and a remainder of 55.
The next digit of our result is 6. 
Result so far: 1046.0
The remainder is 55 after subtracting 450 from 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 6:
550 divided by 75 is 7 with a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 1046.7
The remainder is 25 after subtracting 525 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
When dividing 250 by 75, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 1046.73
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
250 divided by 75 is 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 1046.733
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 1046.733 and a remainder of 0.0025.
