We look at the division of 622902 by 12 
Let's see how many times 12 fits into 622902.

Let's proceed to step 1:
If we divide 6 by 12, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 12

Step 2:
12 can be fit into 62 5 times, resulting in a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 60 from 62 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 12

Moving on to step 3:
12 can be fit into 22 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtracting 12 from 22 leaves us with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 12

On to step 4:
12 goes into 109 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 519.0
Deduct 108 from 109 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 12

Advancing to step 5:
If we divide 10 by 12, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5190.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 12

Let's proceed to step 6:
When dividing 102 by 12, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 51908.0
Subtracting 96 from 102 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 51908.5
Subtracting 60 from 60 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 51908.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 51908.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 51908.5, with a leftover of 0.0.
