78797489 divided by 871 
Our goal is to divide 78797489 by 871.

Let's proceed to step 1:
When dividing 7 by 871, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
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 / 871

On to step 2:
If we divide 78 by 871, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 871

On to step 3:
The number 871 fits into 787 0 times, leaving a remainder of 787.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 787 leaves us with 787.
Include the next digit (9) from the dividend after 787, then repeat: 7879 / 871

Step 4:
7879 divided by 871 is 9 with a remainder of 40.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 7839 from 7879 and we're left with 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 871

Advancing to step 5:
The number 871 fits into 407 0 times, leaving a remainder of 407.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we take 0 away from 407, we end up with 407.
Take the next digit (4) from the dividend and append it to 407, then repeat: 4074 / 871

Moving on to step 6:
871 goes into 4074 4 times with a remainder of 590.
Use 4 as the next digit of our solution. 
Result so far: 904.0
If we subtract 3484 from 4074, we get 590.
Include the next digit (8) from the dividend after 590, then repeat: 5908 / 871

Moving on to step 7:
The number 871 fits into 5908 6 times, leaving a remainder of 682.
Use 6 as the next digit of our solution. 
Result so far: 9046.0
If we take 5226 away from 5908, we end up with 682.
Bring next digit (9) of the dividend behind the 682 and repeat the process: 6829 / 871

Let's proceed to step 8:
871 can be fit into 6829 7 times, resulting in a remainder of 732.
Write down 7 as next digit of the result. 
Result so far: 90467.0
Deduct 6097 from 6829 and we're left with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Advancing to step 9:
7320 divided by 871 is 8 with a remainder of 352.
Use 8 as the next digit of our solution. 
Result so far: 90467.8
If we subtract 6968 from 7320, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 10:
The number 871 fits into 3520 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 90467.84
Subtract 3484 from 3520 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
360 divided by 871 is 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 90467.84
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 12:
If we divide 3600 by 871, we get 4 and a remainder of 116.
The next digit of our result is 4. 
Result so far: 90467.8404
Subtracting 3484 from 3600 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 13:
The number 871 fits into 1160 1 times, leaving a remainder of 289.
The number 1 becomes the next digit in our result. 
Result so far: 90467.84041
The remainder is 289 after subtracting 871 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Going ahead to step 14:
2890 divided by 871 is 3 with a remainder of 277.
The next digit of our result is 3. 
Result so far: 90467.840413
Subtracting 2613 from 2890 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 15:
If we divide 2770 by 871, we get 3 and a remainder of 157.
The number 3 becomes the next digit in our result. 
Result so far: 90467.8404133
The remainder is 157 after subtracting 2613 from 2770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

The final outcome is 90467.8404133, with a leftover of 1.57e-06.
