78771351 ÷ 753 
Our goal is to divide 78771351 by 753.

Moving on to step 1:
When dividing 7 by 753, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 753

On to step 2:
78 divided by 753 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 753

On to step 3:
787 divided by 753 is 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 753 from 787 and we're left with 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 753

Let's proceed to step 4:
753 goes into 347 0 times with a remainder of 347.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 347 and we're left with 347.
Take the next digit (1) from the dividend and append it to 347, then repeat: 3471 / 753

On to step 5:
753 goes into 3471 4 times with a remainder of 459.
The next digit of our result is 4. 
Result so far: 104.0
The remainder is 459 after subtracting 3012 from 3471.
Take the next digit (3) from the dividend and append it to 459, then repeat: 4593 / 753

On to step 6:
753 can be fit into 4593 6 times, resulting in a remainder of 75.
Write down 6 as next digit of the result. 
Result so far: 1046.0
Subtracting 4518 from 4593 leaves us with 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 753

Step 7:
753 can be fit into 755 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 10461.0
If we subtract 753 from 755, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 753

Step 8:
The number 753 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 104610.0
The remainder is 21 after subtracting 0 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
The number 753 fits into 210 0 times, leaving a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 104610.0
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
The number 753 fits into 2100 2 times, leaving a remainder of 594.
Use 2 as the next digit of our solution. 
Result so far: 104610.02
Subtract 1506 from 2100 to get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Moving on to step 11:
753 can be fit into 5940 7 times, resulting in a remainder of 669.
Write down 7 as next digit of the result. 
Result so far: 104610.027
If we take 5271 away from 5940, we end up with 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Going ahead to step 12:
753 goes into 6690 8 times with a remainder of 666.
The next digit of our result is 8. 
Result so far: 104610.0278
Deduct 6024 from 6690 and we're left with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Going ahead to step 13:
753 goes into 6660 8 times with a remainder of 636.
The next digit of our result is 8. 
Result so far: 104610.02788
The remainder is 636 after subtracting 6024 from 6660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The final outcome is 104610.02788, with a leftover of 0.000636.
