We divide 661780 by 50
We want to figure out the number of times 661780 can be divided by 50.

Going ahead to step 1:
6 divided by 50 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 50

On to step 2:
If we divide 66 by 50, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 16 after subtracting 50 from 66.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 50

Step 3:
50 goes into 161 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 150 from 161 leaves us with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 50

Advancing to step 4:
50 can be fit into 117 2 times, resulting in a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 132.0
If we take 100 away from 117, we end up with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 50

Step 5:
The number 50 fits into 178 3 times, leaving a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 1323.0
The remainder is 28 after subtracting 150 from 178.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 50

Advancing to step 6:
280 divided by 50 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 13235.0
Subtract 250 from 280 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
The number 50 fits into 300 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 13235.6
If we subtract 300 from 300, 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.

Step 8:
0 divided by 50 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13235.6
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.

Let's proceed to step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13235.6
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.

The quotient of the division is 13235.6, and the remainder is 0.0.
