77715 divided by 12 
Our goal is to divide 77715 by 12.

Let's proceed to step 1:
When dividing 7 by 12, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 12

Advancing to step 2:
12 goes into 77 6 times with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 72 away from 77, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 12

Advancing to step 3:
When dividing 57 by 12, we get 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we take 48 away from 57, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 12

Moving on to step 4:
When dividing 91 by 12, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 647.0
If we take 84 away from 91, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 12

Let's proceed to step 5:
When dividing 75 by 12, we get 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 6476.0
Deduct 72 from 75 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 6:
30 divided by 12 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 6476.2
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 12 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 6476.25
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.

On to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6476.25
If we subtract 0 from 0, we get 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:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6476.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 6476.25 with a balance of 0.0.
