We look at the division of 871023 by 10 
Let's see how many times 10 fits into 871023.

Step 1:
If we divide 8 by 10, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 10

On to step 2:
If we divide 87 by 10, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 80 from 87 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 10

Let's proceed to step 3:
If we divide 71 by 10, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 87.0
Deduct 70 from 71 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 10

Advancing to step 4:
10 divided by 10 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 871.0
Subtracting 10 from 10 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 10

Advancing to step 5:
The number 10 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 8710.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 10

Going ahead to step 6:
The number 10 fits into 23 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 87102.0
If we take 20 away from 23, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 10, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 87102.3
If we take 30 away from 30, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 87102.3
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 87102.3
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 87102.3, with a leftover of 0.0.
