Let's divide 78666368 by 878
We want to figure out the number of times 78666368 can be divided by 878.

Let's proceed to step 1:
878 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 878

Step 2:
When dividing 78 by 878, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 878

Going ahead to step 3:
878 can be fit into 786 0 times, resulting in a remainder of 786.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 786, we get 786.
Bring next digit (6) of the dividend behind the 786 and repeat the process: 7866 / 878

Moving on to step 4:
The number 878 fits into 7866 8 times, leaving a remainder of 842.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 842 after subtracting 7024 from 7866.
Bring next digit (6) of the dividend behind the 842 and repeat the process: 8426 / 878

Let's proceed to step 5:
The number 878 fits into 8426 9 times, leaving a remainder of 524.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtracting 7902 from 8426 leaves us with 524.
Bring next digit (3) of the dividend behind the 524 and repeat the process: 5243 / 878

Step 6:
If we divide 5243 by 878, we get 5 and a remainder of 853.
Put 5 as the next digit of the answer. 
Result so far: 895.0
If we take 4390 away from 5243, we end up with 853.
Append the next digit (6) from the dividend to 853 and continue with: 8536 / 878

Let's proceed to step 7:
When dividing 8536 by 878, we get 9 with a remainder of 634.
Put 9 as the next digit of the answer. 
Result so far: 8959.0
Subtracting 7902 from 8536 leaves us with 634.
Grab the next digit (8) from the dividend, add it to 634, then carry on: 6348 / 878

On to step 8:
If we divide 6348 by 878, we get 7 and a remainder of 202.
The number 7 becomes the next digit in our result. 
Result so far: 89597.0
The remainder is 202 after subtracting 6146 from 6348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 9:
If we divide 2020 by 878, we get 2 and a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 89597.2
The remainder is 264 after subtracting 1756 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 10:
878 can be fit into 2640 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 89597.23
If we subtract 2634 from 2640, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
878 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 89597.23
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
878 can be fit into 600 0 times, resulting in a remainder of 600.
The next digit of our result is 0. 
Result so far: 89597.23
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The quotient of the division is 89597.23, and the remainder is 0.006.
