Let's divide 855237 by 50
We're looking to find how many times 50 goes into 855237.

Going ahead to step 1:
The number 50 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 50

On to step 2:
The number 50 fits into 85 1 times, leaving a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 50 from 85 to get 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 50

On to step 3:
If we divide 355 by 50, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 350 from 355, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 50

On to step 4:
50 goes into 52 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Subtracting 50 from 52 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 50

On to step 5:
23 divided by 50 is 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 1710.0
Subtracting 0 from 23 leaves us with 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 50

Step 6:
50 can be fit into 237 4 times, resulting in a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 17104.0
Subtracting 200 from 237 leaves us 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.

Let's proceed to step 7:
The number 50 fits into 370 7 times, leaving a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 17104.7
If we take 350 away from 370, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 50 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 17104.74
Deduct 200 from 200 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.

Step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17104.74
Subtract 0 from 0 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.

Going ahead to step 10:
0 divided by 50 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17104.74
Deduct 0 from 0 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.

The quotient of the division is 17104.74, and the remainder is 0.0.
