We divide 813531 by 50
We're looking to find how many times 50 goes into 813531.

Step 1:
50 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 50

Advancing to step 2:
50 can be fit into 81 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 31 after subtracting 50 from 81.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 50

On to step 3:
50 goes into 313 6 times with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 13 after subtracting 300 from 313.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 50

Moving on to step 4:
When dividing 135 by 50, we get 2 with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 162.0
Deduct 100 from 135 and we're left with 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 50

Going ahead to step 5:
50 goes into 353 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 1627.0
Deduct 350 from 353 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 50

Going ahead to step 6:
If we divide 31 by 50, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 16270.0
Subtracting 0 from 31 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
When dividing 310 by 50, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 16270.6
If we subtract 300 from 310, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
50 goes into 100 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 16270.62
Deduct 100 from 100 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:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16270.62
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.

On to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16270.62
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 final result is 16270.62 with a remainder of 0.0.
