We look at the division of 553391 by 12 
We want to divide 553391 by 12.

Going ahead to step 1:
12 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 12

Let's proceed to step 2:
The number 12 fits into 55 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 48 from 55 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 12

Let's proceed to step 3:
12 can be fit into 73 6 times, resulting in a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtracting 72 from 73 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 12

Moving on to step 4:
When dividing 13 by 12, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 461.0
If we take 12 away from 13, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 12

Advancing 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: 4611.0
Deduct 12 from 19 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 12

Going ahead to step 6:
The number 12 fits into 71 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 46115.0
The remainder is 11 after subtracting 60 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
If we divide 110 by 12, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 46115.9
Subtracting 108 from 110 leaves us 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.

Step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 46115.91
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.

On to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 46115.916
Subtracting 72 from 80 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.

Going ahead to step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 46115.9166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 46115.9166 with a remaining 8e-05.
