We look at the division of 790861 by 50 
We're looking to find how many times 50 goes into 790861.

On to step 1:
If we divide 7 by 50, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 50

Going ahead to step 2:
50 goes into 79 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 50 from 79 and we're left with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 50

Step 3:
The number 50 fits into 290 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 250 from 290 and we're left with 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 50

Step 4:
When dividing 408 by 50, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 158.0
The remainder is 8 after subtracting 400 from 408.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 50

Step 5:
50 goes into 86 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1581.0
Subtracting 50 from 86 leaves us with 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 50

On to step 6:
361 divided by 50 is 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 15817.0
Subtracting 350 from 361 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
110 divided by 50 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 15817.2
Subtract 100 from 110 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 50 fits into 100 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 15817.22
If we take 100 away from 100, 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.

After the division, we end up with 15817.22 and a remainder of 0.0.
