871648 ÷ 50 
We want to divide 871648 by 50.

Step 1:
The number 50 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
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 / 50

Step 2:
87 divided by 50 is 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 50 away from 87, we end up with 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 50

Advancing to step 3:
50 goes into 371 7 times with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 350 from 371 to get 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 50

Step 4:
216 divided by 50 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
Deduct 200 from 216 and we're left with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 50

Let's proceed to step 5:
The number 50 fits into 164 3 times, leaving a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 1743.0
Subtract 150 from 164 to get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 50

Going ahead to step 6:
If we divide 148 by 50, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 17432.0
If we subtract 100 from 148, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
480 divided by 50 is 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 17432.9
Subtracting 450 from 480 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
50 can be fit into 300 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 17432.96
Deduct 300 from 300 and we're left 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.

Moving on to step 9:
0 divided by 50 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17432.96
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.

Let's proceed to step 10:
0 divided by 50 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17432.96
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.

The quotient of the division is 17432.96, and the remainder is 0.0.
