We're dividing 864270 by 50 
We want to figure out the number of times 864270 can be divided by 50.

Going ahead to step 1:
If we divide 8 by 50, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 50

Moving on to step 2:
50 goes into 86 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
If we take 50 away from 86, we end up with 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 50

Step 3:
If we divide 364 by 50, we get 7 and a remainder of 14.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 350 from 364, we get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 50

Advancing to step 4:
50 can be fit into 142 2 times, resulting in a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Deduct 100 from 142 and we're left with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 50

Moving on to step 5:
If we divide 427 by 50, we get 8 and a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 1728.0
Deduct 400 from 427 and we're left with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 50

Let's proceed to step 6:
When dividing 270 by 50, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 17285.0
If we subtract 250 from 270, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
If we divide 200 by 50, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 17285.4
Subtract 200 from 200 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.

On to step 8:
If we divide 0 by 50, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17285.4
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.

On to step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17285.4
Deduct 0 from 0 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 outcome is 17285.4, with a leftover of 0.0.
