We look at the division of 651906 by 12 
We want to figure out the number of times 651906 can be divided by 12.

Advancing to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 12

On to step 2:
When dividing 65 by 12, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 60 away from 65, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 12

On to step 3:
If we divide 51 by 12, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtracting 48 from 51 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 12

On to step 4:
12 goes into 39 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 543.0
The remainder is 3 after subtracting 36 from 39.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 12

Moving on to step 5:
30 divided by 12 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 5432.0
If we subtract 24 from 30, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 12

Step 6:
12 goes into 66 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 54325.0
Deduct 60 from 66 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.

Going ahead to step 7:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 54325.5
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.

Step 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54325.5
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.

Going ahead to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 54325.5
If we take 0 away from 0, 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.

The quotient of the division is 54325.5, and the remainder is 0.0.
