Let's divide 551680 by 12
We're looking to find how many times 12 goes into 551680.

Going ahead to step 1:
5 divided by 12 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 12

Step 2:
The number 12 fits into 55 4 times, leaving a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 7 after subtracting 48 from 55.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 12

Going ahead to step 3:
The number 12 fits into 71 5 times, leaving a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 60 from 71 leaves us with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 12

Going ahead to step 4:
If we divide 116 by 12, we get 9 and a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 459.0
Deduct 108 from 116 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 12

Let's proceed to step 5:
When dividing 88 by 12, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 4597.0
If we take 84 away from 88, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 12

On to step 6:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 45973.0
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 45973.3
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 45973.33
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 45973.33 with a remainder of 0.004.
