We divide 621289 by 50
Let's see how many times 50 fits into 621289.

Let's proceed to step 1:
The number 50 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 50

Let's proceed to step 2:
50 can be fit into 62 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 50 from 62 to get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 50

On to step 3:
50 can be fit into 121 2 times, resulting in a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 21 after subtracting 100 from 121.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 50

Step 4:
If we divide 212 by 50, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we subtract 200 from 212, we get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 50

Advancing to step 5:
50 can be fit into 128 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 1242.0
Deduct 100 from 128 and we're left with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 50

Step 6:
50 goes into 289 5 times with a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 12425.0
If we subtract 250 from 289, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
50 can be fit into 390 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 12425.7
Subtracting 350 from 390 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
50 goes into 400 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 12425.78
If we take 400 away from 400, 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.

Step 9:
50 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12425.78
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.

Going ahead to step 10:
When dividing 0 by 50, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12425.78
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.

The quotient of the division is 12425.78, and the remainder is 0.0.
