872858 ÷ 50 
Let's see how many times 50 fits into 872858.

Let's proceed to step 1:
When dividing 8 by 50, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 50

On to step 2:
50 goes into 87 1 times with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 50 from 87 and we're left with 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 50

On to step 3:
372 divided by 50 is 7 with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 350 from 372, we get 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 50

On to step 4:
50 goes into 228 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
Deduct 200 from 228 and we're left with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 50

Going ahead to step 5:
285 divided by 50 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1745.0
If we take 250 away from 285, we end up with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 50

On to step 6:
The number 50 fits into 358 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 17457.0
Subtracting 350 from 358 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.

Moving on to step 7:
50 goes into 80 1 times with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 17457.1
Subtracting 50 from 80 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.

Going ahead to step 8:
300 divided by 50 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 17457.16
Subtract 300 from 300 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17457.16
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17457.16
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 17457.16 with a remaining 0.0.
