913449 ÷ 12 
Let's see how many times 12 fits into 913449.

Going ahead to step 1:
12 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 12

Let's proceed to step 2:
The number 12 fits into 91 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 84 from 91 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 12

Going ahead to step 3:
12 can be fit into 73 6 times, resulting in a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Deduct 72 from 73 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 12

Step 4:
The number 12 fits into 14 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 761.0
Deduct 12 from 14 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 12

Advancing to step 5:
12 goes into 24 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 7612.0
If we take 24 away from 24, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 12

Let's proceed to step 6:
9 divided by 12 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 76120.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
When dividing 90 by 12, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 76120.7
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.
Record the quotient 5 as the next digit in the result. 
Result so far: 76120.75
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:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 76120.75
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.

Going ahead to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 76120.75
Deduct 0 from 0 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.

The final result is 76120.75 with a remainder of 0.0.
