We look at the division of 870633 by 50 
We want to figure out the number of times 870633 can be divided by 50.

Going ahead to step 1:
The number 50 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 50

On to step 2:
87 divided by 50 is 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 50 from 87 leaves us with 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 50

On to step 3:
The number 50 fits into 370 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 350 away from 370, we end up with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 50

Step 4:
The number 50 fits into 206 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 174.0
Deduct 200 from 206 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 50

Moving on to step 5:
If we divide 63 by 50, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1741.0
If we take 50 away from 63, we end up with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 50

Moving on to step 6:
If we divide 133 by 50, we get 2 and a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 17412.0
If we take 100 away from 133, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
50 goes into 330 6 times with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 17412.6
Deduct 300 from 330 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
When dividing 300 by 50, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 17412.66
The remainder is 0 after subtracting 300 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 17412.66, and the remainder is 0.0.
