871958 ÷ 12 
Let's see how many times 12 fits into 871958.

Going ahead to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 12

Going ahead to step 2:
When dividing 87 by 12, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 3 after subtracting 84 from 87.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 12

Let's proceed to step 3:
When dividing 31 by 12, we get 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 7 after subtracting 24 from 31.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 12

On to step 4:
The number 12 fits into 79 6 times, leaving a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 726.0
If we subtract 72 from 79, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 12

Moving on to step 5:
12 goes into 75 6 times with a remainder of 3.
The next digit of our result is 6. 
Result so far: 7266.0
If we take 72 away from 75, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 12

Step 6:
If we divide 38 by 12, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 72663.0
Deduct 36 from 38 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
12 goes into 20 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 72663.1
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 72663.16
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
12 goes into 80 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 72663.166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 72663.166, and the remainder is 0.0008.
