68988039 ÷ 878 
Let's see how many times 878 fits into 68988039.

Advancing to step 1:
When dividing 6 by 878, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 878

Advancing to step 2:
68 divided by 878 is 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Bring next digit (9) of the dividend behind the 68 and repeat the process: 689 / 878

Going ahead to step 3:
When dividing 689 by 878, we get 0 with a remainder of 689.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 689 to get 689.
Grab the next digit (8) from the dividend, add it to 689, then carry on: 6898 / 878

Advancing to step 4:
The number 878 fits into 6898 7 times, leaving a remainder of 752.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 6146 from 6898, we get 752.
Include the next digit (8) from the dividend after 752, then repeat: 7528 / 878

Let's proceed to step 5:
If we divide 7528 by 878, we get 8 and a remainder of 504.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 7024 from 7528 and we're left with 504.
Append the next digit (0) from the dividend to 504 and continue with: 5040 / 878

Going ahead to step 6:
The number 878 fits into 5040 5 times, leaving a remainder of 650.
The number 5 becomes the next digit in our result. 
Result so far: 785.0
If we subtract 4390 from 5040, we get 650.
Grab the next digit (3) from the dividend, add it to 650, then carry on: 6503 / 878

Advancing to step 7:
878 goes into 6503 7 times with a remainder of 357.
The next digit of our result is 7. 
Result so far: 7857.0
Subtracting 6146 from 6503 leaves us with 357.
Append the next digit (9) from the dividend to 357 and continue with: 3579 / 878

Step 8:
878 goes into 3579 4 times with a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 78574.0
Subtract 3512 from 3579 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 9:
878 goes into 670 0 times with a remainder of 670.
Write down 0 as next digit of the result. 
Result so far: 78574.0
If we subtract 0 from 670, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 10:
When dividing 6700 by 878, we get 7 with a remainder of 554.
Record the quotient 7 as the next digit in the result. 
Result so far: 78574.07
If we take 6146 away from 6700, we end up with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 11:
878 can be fit into 5540 6 times, resulting in a remainder of 272.
The next digit of our result is 6. 
Result so far: 78574.076
Deduct 5268 from 5540 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 12:
When dividing 2720 by 878, we get 3 with a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 78574.0763
The remainder is 86 after subtracting 2634 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 13:
If we divide 860 by 878, we get 0 and a remainder of 860.
The next digit of our result is 0. 
Result so far: 78574.0763
Subtract 0 from 860 to get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Step 14:
878 can be fit into 8600 9 times, resulting in a remainder of 698.
Put 9 as the next digit of the answer. 
Result so far: 78574.076309
Subtract 7902 from 8600 to get 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

On to step 15:
The number 878 fits into 6980 7 times, leaving a remainder of 834.
The number 7 becomes the next digit in our result. 
Result so far: 78574.0763097
If we subtract 6146 from 6980, we get 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

On to step 16:
If we divide 8340 by 878, we get 9 and a remainder of 438.
Record the quotient 9 as the next digit in the result. 
Result so far: 78574.07630979
If we take 7902 away from 8340, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The final result is 78574.07630979 with a remainder of 4.38e-07.
