We look at the division of 646340 by 50 
We want to divide 646340 by 50.

Moving on to step 1:
The number 50 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 50

Let's proceed to step 2:
If we divide 64 by 50, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 50 from 64, we get 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 50

Advancing to step 3:
The number 50 fits into 146 2 times, leaving a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 100 from 146 leaves us with 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 50

Moving on to step 4:
The number 50 fits into 463 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 129.0
If we take 450 away from 463, we end up with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 50

On to step 5:
50 goes into 134 2 times with a remainder of 34.
The next digit of our result is 2. 
Result so far: 1292.0
If we subtract 100 from 134, we get 34.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 50

Moving on to step 6:
If we divide 340 by 50, we get 6 and a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 12926.0
Subtracting 300 from 340 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.

Moving on to step 7:
50 can be fit into 400 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 12926.8
If we subtract 400 from 400, 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.

Advancing to step 8:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12926.8
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.

Going ahead to step 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12926.8
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 12926.8, and the remainder is 0.0.
