903879 ÷ 12 
Our goal is to divide 903879 by 12.

Advancing to step 1:
The number 12 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 12

Advancing to step 2:
12 can be fit into 90 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 84 from 90 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 12

Let's proceed to step 3:
When dividing 63 by 12, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 75.0
Deduct 60 from 63 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 12

Moving on to step 4:
The number 12 fits into 38 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 753.0
Subtracting 36 from 38 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 12

Moving on to step 5:
12 goes into 27 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 7532.0
Subtracting 24 from 27 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 12

Advancing to step 6:
12 can be fit into 39 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 75323.0
If we subtract 36 from 39, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 75323.2
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 75323.25
Deduct 60 from 60 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.

Advancing to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 75323.25
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 10:
0 divided by 12 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 75323.25
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.

In conclusion, the division gives 75323.25 with a balance of 0.0.
