870522 ÷ 50 
We want to figure out the number of times 870522 can be divided by 50.

Step 1:
The number 50 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 50

On to step 2:
50 goes into 87 1 times with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 50 from 87 leaves us with 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 50

Moving on to step 3:
50 goes into 370 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 350 from 370 leaves us with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 50

Advancing to step 4:
The number 50 fits into 205 4 times, leaving a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
If we subtract 200 from 205, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 50

Going ahead to step 5:
The number 50 fits into 52 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1741.0
If we subtract 50 from 52, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 50

Advancing to step 6:
22 divided by 50 is 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 17410.0
Subtract 0 from 22 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
If we divide 220 by 50, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 17410.4
If we take 200 away from 220, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 50 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 17410.44
Deduct 200 from 200 and we're left 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.

The final result is 17410.44 with a remainder of 0.0.
