We divide 624866 by 12
We're looking to find how many times 12 goes into 624866.

Going ahead to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 12

Moving on to step 2:
12 goes into 62 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 2 after subtracting 60 from 62.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 12

Going ahead to step 3:
12 goes into 24 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Deduct 24 from 24 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 12

Step 4:
12 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 520.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 12

On to step 5:
86 divided by 12 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 5207.0
Subtracting 84 from 86 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 12

Let's proceed to step 6:
When dividing 26 by 12, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 52072.0
Subtracting 24 from 26 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.

Going ahead to step 7:
When dividing 20 by 12, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 52072.1
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:
If we divide 80 by 12, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 52072.16
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.

Moving on to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 52072.166
Subtract 72 from 80 to 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.

The final outcome is 52072.166, with a leftover of 0.0008.
