We're dividing 858459 by 48 
We want to divide 858459 by 48.

On to step 1:
8 divided by 48 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 48

On to step 2:
The number 48 fits into 85 1 times, leaving a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 37 after subtracting 48 from 85.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 48

On to step 3:
48 can be fit into 378 7 times, resulting in a remainder of 42.
The next digit of our result is 7. 
Result so far: 17.0
If we take 336 away from 378, we end up with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 48

Step 4:
The number 48 fits into 424 8 times, leaving a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
The remainder is 40 after subtracting 384 from 424.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 48

Let's proceed to step 5:
48 goes into 405 8 times with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 1788.0
If we take 384 away from 405, we end up with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 48

On to step 6:
219 divided by 48 is 4 with a remainder of 27.
The next digit of our result is 4. 
Result so far: 17884.0
The remainder is 27 after subtracting 192 from 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
48 goes into 270 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 17884.5
The remainder is 30 after subtracting 240 from 270.
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:
48 goes into 300 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 17884.56
The remainder is 12 after subtracting 288 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
When dividing 120 by 48, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 17884.562
The remainder is 24 after subtracting 96 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
When dividing 240 by 48, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 17884.5625
If we take 240 away from 240, 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 11:
48 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17884.5625
The remainder is 0 after subtracting 0 from 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 12:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17884.5625
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.

In conclusion, the division gives 17884.5625 with a balance of 0.0.
