19071878 ÷ 871 
We want to figure out the number of times 19071878 can be divided by 871.

Let's proceed to step 1:
The number 871 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 871

Advancing to step 2:
If we divide 19 by 871, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 871

Going ahead to step 3:
871 can be fit into 190 0 times, resulting in a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 190 and we're left with 190.
Include the next digit (7) from the dividend after 190, then repeat: 1907 / 871

Let's proceed to step 4:
The number 871 fits into 1907 2 times, leaving a remainder of 165.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 165 after subtracting 1742 from 1907.
Fetch the next digit (1) from the dividend, attach it to 165 and continue: 1651 / 871

Let's proceed to step 5:
871 goes into 1651 1 times with a remainder of 780.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 871 from 1651 to get 780.
Fetch the next digit (8) from the dividend, attach it to 780 and continue: 7808 / 871

Moving on to step 6:
The number 871 fits into 7808 8 times, leaving a remainder of 840.
The next digit of our result is 8. 
Result so far: 218.0
If we take 6968 away from 7808, we end up with 840.
Grab the next digit (7) from the dividend, add it to 840, then carry on: 8407 / 871

On to step 7:
8407 divided by 871 is 9 with a remainder of 568.
Record the quotient 9 as the next digit in the result. 
Result so far: 2189.0
If we subtract 7839 from 8407, we get 568.
Include the next digit (8) from the dividend after 568, then repeat: 5688 / 871

On to step 8:
When dividing 5688 by 871, we get 6 with a remainder of 462.
Write down 6 as next digit of the result. 
Result so far: 21896.0
If we take 5226 away from 5688, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 9:
871 goes into 4620 5 times with a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 21896.5
Subtracting 4355 from 4620 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 10:
871 goes into 2650 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 21896.53
Deduct 2613 from 2650 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
871 can be fit into 370 0 times, resulting in a remainder of 370.
The next digit of our result is 0. 
Result so far: 21896.53
Subtracting 0 from 370 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 12:
The number 871 fits into 3700 4 times, leaving a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 21896.5304
Subtract 3484 from 3700 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 13:
If we divide 2160 by 871, we get 2 and a remainder of 418.
The next digit of our result is 2. 
Result so far: 21896.53042
Subtracting 1742 from 2160 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 14:
4180 divided by 871 is 4 with a remainder of 696.
The number 4 becomes the next digit in our result. 
Result so far: 21896.530424
If we subtract 3484 from 4180, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

On to step 15:
871 can be fit into 6960 7 times, resulting in a remainder of 863.
The next digit of our result is 7. 
Result so far: 21896.5304247
If we subtract 6097 from 6960, we get 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Let's proceed to step 16:
The number 871 fits into 8630 9 times, leaving a remainder of 791.
The number 9 becomes the next digit in our result. 
Result so far: 21896.53042479
Deduct 7839 from 8630 and we're left with 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Our division results in 21896.53042479 with a remaining 7.91e-07.
