We're dividing 791445 by 50 
We want to figure out the number of times 791445 can be divided by 50.

On to step 1:
50 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 50

On to step 2:
If we divide 79 by 50, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 50 from 79, we get 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 50

On to step 3:
50 goes into 291 5 times with a remainder of 41.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 250 away from 291, we end up with 41.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 50

Step 4:
If we divide 414 by 50, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 158.0
The remainder is 14 after subtracting 400 from 414.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 50

On to step 5:
If we divide 144 by 50, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 1582.0
If we subtract 100 from 144, we get 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 50

Step 6:
When dividing 445 by 50, we get 8 with a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 15828.0
Deduct 400 from 445 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
50 can be fit into 450 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 15828.9
If we subtract 450 from 450, 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:
If we divide 0 by 50, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15828.9
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.

Moving on to step 9:
50 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15828.9
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.

Our division results in 15828.9 with a remaining 0.0.
