We look at the division of 910305 by 12 
Let's see how many times 12 fits into 910305.

On to step 1:
9 divided by 12 is 0 with 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.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 12

Advancing to step 2:
When dividing 91 by 12, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 84 from 91, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 12

Let's proceed to step 3:
12 goes into 70 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Deduct 60 from 70 and we're left with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 12

Going ahead to step 4:
103 divided by 12 is 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 758.0
If we subtract 96 from 103, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 12

Let's proceed to step 5:
12 can be fit into 70 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 7585.0
Subtract 60 from 70 to get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 12

Moving on to step 6:
When dividing 105 by 12, we get 8 with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 75858.0
Subtract 96 from 105 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
If we divide 90 by 12, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 75858.7
Subtracting 84 from 90 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.

Advancing to 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: 75858.75
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 75858.75
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.

On to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 75858.75
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.

After the division, we end up with 75858.75 and a remainder of 0.0.
