942509 ÷ 12 
Let's see how many times 12 fits into 942509.

Advancing to step 1:
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: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 12

Step 2:
94 divided by 12 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 84 from 94, we get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 12

Going ahead to step 3:
When dividing 102 by 12, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we subtract 96 from 102, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 12

Step 4:
12 goes into 65 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 785.0
If we take 60 away from 65, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 12

Step 5:
12 goes into 50 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 7854.0
If we take 48 away from 50, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 12

Moving on to step 6:
If we divide 29 by 12, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 78542.0
If we subtract 24 from 29, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
If we divide 50 by 12, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 78542.4
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 78542.41
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 78542.416
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
80 divided by 12 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 78542.4166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 78542.4166, and the remainder is 8e-05.
