We look at the division of 391045 by 50 
We want to divide 391045 by 50.

Let's proceed to step 1:
3 divided by 50 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 50

On to step 2:
The number 50 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 50

On to step 3:
50 goes into 391 7 times with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 350 away from 391, we end up with 41.
Bring next digit (0) of the dividend behind the 41 and repeat the process: 410 / 50

Let's proceed to step 4:
When dividing 410 by 50, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 400 from 410 and we're left with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 50

Let's proceed to step 5:
50 goes into 104 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 782.0
The remainder is 4 after subtracting 100 from 104.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 50

On to step 6:
50 can be fit into 45 0 times, resulting in a remainder of 45.
The next digit of our result is 0. 
Result so far: 7820.0
The remainder is 45 after subtracting 0 from 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
50 goes into 450 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 7820.9
Subtract 450 from 450 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.

On to step 8:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7820.9
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.

Going ahead to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7820.9
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 7820.9, with a leftover of 0.0.
