921345 divided by 12 
We want to figure out the number of times 921345 can be divided by 12.

Let's proceed 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
Subtract 0 from 9 to get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 12

On to step 2:
92 divided by 12 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 84 from 92 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 12

Step 3:
12 can be fit into 81 6 times, resulting in a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
If we subtract 72 from 81, we get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 12

Moving on to step 4:
The number 12 fits into 93 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 767.0
Subtracting 84 from 93 leaves us with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 12

On to step 5:
When dividing 94 by 12, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 7677.0
If we take 84 away from 94, we end up with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 12

Going ahead to step 6:
The number 12 fits into 105 8 times, leaving a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 76778.0
The remainder is 9 after subtracting 96 from 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
12 goes into 90 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 76778.7
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 76778.75
If we take 60 away from 60, 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.

Advancing to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 76778.75
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.

Let's proceed to step 10:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 76778.75
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 outcome is 76778.75, with a leftover of 0.0.
