We're dividing 628046 by 12 
We want to figure out the number of times 628046 can be divided by 12.

Advancing to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 12

On to step 2:
12 goes into 62 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 60 from 62 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 12

Going ahead to step 3:
12 goes into 28 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtract 24 from 28 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 12

On to step 4:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 523.0
Subtracting 36 from 40 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 12

Step 5:
12 goes into 44 3 times with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 5233.0
The remainder is 8 after subtracting 36 from 44.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 12

Going ahead to step 6:
The number 12 fits into 86 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 52337.0
Deduct 84 from 86 and we're left 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.

On to step 7:
If we divide 20 by 12, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 52337.1
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
80 divided by 12 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 52337.16
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.

Advancing to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 52337.166
If we take 72 away from 80, we end up 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.

The final result is 52337.166 with a remainder of 0.0008.
