71978896 divided by 878 
We want to figure out the number of times 71978896 can be divided by 878.

Advancing to step 1:
7 divided by 878 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 878

Let's proceed to step 2:
If we divide 71 by 878, we get 0 and a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 878

Advancing to step 3:
When dividing 719 by 878, we get 0 with a remainder of 719.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 719 and we're left with 719.
Take the next digit (7) from the dividend and append it to 719, then repeat: 7197 / 878

Advancing to step 4:
When dividing 7197 by 878, we get 8 with a remainder of 173.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7024 away from 7197, we end up with 173.
Take the next digit (8) from the dividend and append it to 173, then repeat: 1738 / 878

Step 5:
1738 divided by 878 is 1 with a remainder of 860.
Write down 1 as next digit of the result. 
Result so far: 81.0
Deduct 878 from 1738 and we're left with 860.
Append the next digit (8) from the dividend to 860 and continue with: 8608 / 878

Going ahead to step 6:
8608 divided by 878 is 9 with a remainder of 706.
Use 9 as the next digit of our solution. 
Result so far: 819.0
If we take 7902 away from 8608, we end up with 706.
Fetch the next digit (9) from the dividend, attach it to 706 and continue: 7069 / 878

Going ahead to step 7:
The number 878 fits into 7069 8 times, leaving a remainder of 45.
Put 8 as the next digit of the answer. 
Result so far: 8198.0
The remainder is 45 after subtracting 7024 from 7069.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 878

Step 8:
When dividing 456 by 878, we get 0 with a remainder of 456.
The number 0 becomes the next digit in our result. 
Result so far: 81980.0
Subtracting 0 from 456 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 9:
If we divide 4560 by 878, we get 5 and a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 81980.5
If we subtract 4390 from 4560, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
If we divide 1700 by 878, we get 1 and a remainder of 822.
Use 1 as the next digit of our solution. 
Result so far: 81980.51
If we subtract 878 from 1700, we get 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Let's proceed to step 11:
878 can be fit into 8220 9 times, resulting in a remainder of 318.
Write down 9 as next digit of the result. 
Result so far: 81980.519
If we subtract 7902 from 8220, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 12:
If we divide 3180 by 878, we get 3 and a remainder of 546.
The number 3 becomes the next digit in our result. 
Result so far: 81980.5193
Subtracting 2634 from 3180 leaves us with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Advancing to step 13:
The number 878 fits into 5460 6 times, leaving a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 81980.51936
The remainder is 192 after subtracting 5268 from 5460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 14:
When dividing 1920 by 878, we get 2 with a remainder of 164.
The number 2 becomes the next digit in our result. 
Result so far: 81980.519362
Deduct 1756 from 1920 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 15:
The number 878 fits into 1640 1 times, leaving a remainder of 762.
The number 1 becomes the next digit in our result. 
Result so far: 81980.5193621
Deduct 878 from 1640 and we're left with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Advancing to step 16:
7620 divided by 878 is 8 with a remainder of 596.
The next digit of our result is 8. 
Result so far: 81980.51936218
Subtracting 7024 from 7620 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

The final outcome is 81980.51936218, with a leftover of 5.96e-07.
