We're dividing 77340 by 12 
We want to figure out the number of times 77340 can be divided by 12.

Moving on to step 1:
12 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 12

Going ahead to step 2:
When dividing 77 by 12, we get 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 72 from 77 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 12

Advancing to step 3:
53 divided by 12 is 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtract 48 from 53 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 12

Moving on to step 4:
When dividing 54 by 12, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 644.0
If we subtract 48 from 54, we get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 12

Moving on to step 5:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6445.0
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.

Moving on to step 6:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6445.0
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.

Advancing to step 7:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6445.0
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 outcome is 6445.0, with a leftover of 0.0.
