We divide 553426 by 12
We're looking to find how many times 12 goes into 553426.

Advancing to step 1:
5 divided by 12 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 12

On to step 2:
12 can be fit into 55 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 48 away from 55, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 12

Moving on to step 3:
12 can be fit into 73 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Deduct 72 from 73 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 12

Step 4:
When dividing 14 by 12, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 461.0
Subtract 12 from 14 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 12

On to step 5:
12 goes into 22 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 4611.0
The remainder is 10 after subtracting 12 from 22.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 12

Step 6:
When dividing 106 by 12, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 46118.0
The remainder is 10 after subtracting 96 from 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
When dividing 100 by 12, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 46118.8
If we subtract 96 from 100, 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.

Going ahead to step 8:
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: 46118.83
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.

Step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 46118.833
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.

Our division results in 46118.833 with a remaining 0.0004.
