We divide 905199 by 12
We want to divide 905199 by 12.

Let's proceed to step 1:
12 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 12

Advancing to step 2:
If we divide 90 by 12, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 84 away from 90, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 12

Step 3:
12 can be fit into 65 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtract 60 from 65 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 12

On to step 4:
If we divide 51 by 12, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 754.0
Subtract 48 from 51 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 12

On to step 5:
The number 12 fits into 39 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 7543.0
If we take 36 away from 39, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 12

Step 6:
The number 12 fits into 39 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 75433.0
Subtracting 36 from 39 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 75433.2
If we subtract 24 from 30, we 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.

Step 8:
12 goes into 60 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 75433.25
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.

Let's proceed to step 9:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 75433.25
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.

On to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 75433.25
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.

The final result is 75433.25 with a remainder of 0.0.
