We're dividing 858264 by 50 
Let's see how many times 50 fits into 858264.

On 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
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 50

Step 2:
When dividing 85 by 50, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 50 from 85, we get 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 50

On to step 3:
50 goes into 358 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 350 from 358 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 50

Going ahead to step 4:
The number 50 fits into 82 1 times, leaving a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
Subtract 50 from 82 to get 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 50

On to step 5:
If we divide 326 by 50, we get 6 and a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 1716.0
If we take 300 away from 326, we end up with 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 50

On to step 6:
If we divide 264 by 50, we get 5 and a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 17165.0
Subtracting 250 from 264 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
The number 50 fits into 140 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 17165.2
Subtracting 100 from 140 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.

On to step 8:
If we divide 400 by 50, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 17165.28
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17165.28
Subtract 0 from 0 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.

Step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17165.28
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 17165.28 with a balance of 0.0.
