780637 ÷ 50 
We're looking to find how many times 50 goes into 780637.

Step 1:
If we divide 7 by 50, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 50

Going ahead to step 2:
When dividing 78 by 50, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 50 from 78, we get 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 50

Let's proceed to step 3:
When dividing 280 by 50, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 250 away from 280, we end up with 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 50

On to step 4:
If we divide 306 by 50, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
Deduct 300 from 306 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 50

Let's proceed to step 5:
50 goes into 63 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1561.0
If we subtract 50 from 63, we get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 50

Going ahead to step 6:
50 goes into 137 2 times with a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 15612.0
The remainder is 37 after subtracting 100 from 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
370 divided by 50 is 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 15612.7
If we subtract 350 from 370, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 50, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 15612.74
Subtracting 200 from 200 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.

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: 15612.74
Subtracting 0 from 0 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.

On to step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15612.74
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 final outcome is 15612.74, with a leftover of 0.0.
