663928 divided by 50 
We're looking to find how many times 50 goes into 663928.

Step 1:
50 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 50

Step 2:
50 can be fit into 66 1 times, resulting in a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 50 from 66 to get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 50

On to step 3:
When dividing 163 by 50, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 150 from 163 and we're left with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 50

Let's proceed to step 4:
50 can be fit into 139 2 times, resulting in a remainder of 39.
The next digit of our result is 2. 
Result so far: 132.0
Deduct 100 from 139 and we're left with 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 50

On to step 5:
50 can be fit into 392 7 times, resulting in a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 1327.0
Subtracting 350 from 392 leaves us with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 50

Moving on to step 6:
When dividing 428 by 50, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 13278.0
Deduct 400 from 428 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
280 divided by 50 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 13278.5
Deduct 250 from 280 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 50, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 13278.56
If we take 300 away from 300, 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.

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: 13278.56
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.

On to step 10:
50 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13278.56
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.

After the division, we end up with 13278.56 and a remainder of 0.0.
