We divide 621036 by 50
Our goal is to divide 621036 by 50.

Step 1:
When dividing 6 by 50, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 50

Going ahead to step 2:
50 goes into 62 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 50 from 62 to get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 50

On to step 3:
50 goes into 121 2 times with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 100 away from 121, we end up with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 50

Moving on to step 4:
50 can be fit into 210 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 124.0
Subtract 200 from 210 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 50

Going ahead to step 5:
50 goes into 103 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 1242.0
If we subtract 100 from 103, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 50

Moving on to step 6:
When dividing 36 by 50, we get 0 with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 12420.0
Deduct 0 from 36 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
If we divide 360 by 50, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 12420.7
If we take 350 away from 360, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
50 can be fit into 100 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 12420.72
Subtracting 100 from 100 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.

Going ahead to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12420.72
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.

Let's proceed to step 10:
If we divide 0 by 50, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 12420.72
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.

The final outcome is 12420.72, with a leftover of 0.0.
