We look at the division of 485939 by 50 
We want to figure out the number of times 485939 can be divided by 50.

Step 1:
4 divided by 50 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 50

Going ahead to step 2:
50 goes into 48 0 times with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 50

Let's proceed to step 3:
When dividing 485 by 50, we get 9 with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 450 from 485 and we're left with 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 50

Step 4:
If we divide 359 by 50, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 97.0
If we take 350 away from 359, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 50

Going ahead to step 5:
93 divided by 50 is 1 with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 971.0
If we take 50 away from 93, we end up with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 50

Step 6:
When dividing 439 by 50, we get 8 with a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 9718.0
Subtracting 400 from 439 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
The number 50 fits into 390 7 times, leaving a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 9718.7
Subtracting 350 from 390 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
50 can be fit into 400 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 9718.78
Subtract 400 from 400 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:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9718.78
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 10:
0 divided by 50 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9718.78
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 9718.78 with a remaining 0.0.
