We're dividing 774198 by 12 
We want to divide 774198 by 12.

Going ahead to step 1:
7 divided by 12 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 12

Advancing to step 2:
The number 12 fits into 77 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 72 from 77 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 12

On to step 3:
If we divide 54 by 12, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Subtract 48 from 54 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 12

Let's proceed to step 4:
61 divided by 12 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 645.0
Subtracting 60 from 61 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 12

Let's proceed to step 5:
19 divided by 12 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 6451.0
Deduct 12 from 19 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 12

Let's proceed to step 6:
12 can be fit into 78 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 64516.0
Deduct 72 from 78 and we're left with 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.
Record the quotient 5 as the next digit in the result. 
Result so far: 64516.5
Subtract 60 from 60 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.

Let's proceed to step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 64516.5
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.

Step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 64516.5
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.

After the division, we end up with 64516.5 and a remainder of 0.0.
