Let's divide 771215 by 12
Let's see how many times 12 fits into 771215.

Step 1:
12 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 12

Step 2:
When dividing 77 by 12, we get 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 72 from 77 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 12

On to step 3:
When dividing 51 by 12, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtracting 48 from 51 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 12

On to step 4:
12 can be fit into 32 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 642.0
The remainder is 8 after subtracting 24 from 32.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 12

On to step 5:
12 can be fit into 81 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 6426.0
If we take 72 away from 81, we end up with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 12

Step 6:
The number 12 fits into 95 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 64267.0
If we subtract 84 from 95, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
110 divided by 12 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 64267.9
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 64267.91
Subtracting 12 from 20 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 9:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 64267.916
Deduct 72 from 80 and we're left 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.

Step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 64267.9166
Deduct 72 from 80 and we're left 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.

After the division, we end up with 64267.9166 and a remainder of 8e-05.
