We're dividing 858879 by 48 
Let's see how many times 48 fits into 858879.

Going ahead to step 1:
If we divide 8 by 48, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 48

Step 2:
If we divide 85 by 48, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 48 from 85 to get 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 48

Let's proceed to step 3:
48 goes into 378 7 times with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 336 from 378 leaves us with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 48

Moving on to step 4:
When dividing 428 by 48, we get 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 178.0
If we subtract 384 from 428, we get 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 48

On to step 5:
If we divide 447 by 48, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 1789.0
Subtract 432 from 447 to get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 48

Step 6:
When dividing 159 by 48, we get 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 17893.0
Deduct 144 from 159 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
The number 48 fits into 150 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 17893.3
Subtracting 144 from 150 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
60 divided by 48 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 17893.31
Subtract 48 from 60 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 48 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 17893.312
Deduct 96 from 120 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
48 goes into 240 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 17893.3125
Subtract 240 from 240 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.

Let's proceed to step 11:
If we divide 0 by 48, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17893.3125
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.

Step 12:
When dividing 0 by 48, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17893.3125
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.

The final outcome is 17893.3125, with a leftover of 0.0.
