We look at the division of 878497 by 48 
We want to divide 878497 by 48.

Going ahead 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
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 48

Going ahead to step 2:
48 can be fit into 87 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 48 from 87 to get 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 48

On to step 3:
When dividing 398 by 48, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 384 from 398 to get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 48

Going ahead to step 4:
When dividing 144 by 48, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 183.0
Deduct 144 from 144 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 48

On to step 5:
When dividing 9 by 48, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 1830.0
If we take 0 away from 9, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 48

Moving on to step 6:
The number 48 fits into 97 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 18302.0
Subtract 96 from 97 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
48 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 18302.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 48 fits into 100 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 18302.02
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
48 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 18302.02
Deduct 0 from 40 and we're left 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.

Step 10:
48 goes into 400 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 18302.0208
If we take 384 away from 400, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 18302.02083
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
160 divided by 48 is 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 18302.020833
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 18302.020833, with a leftover of 1.6e-06.
