We look at the division of 618770 by 12 
Let's see how many times 12 fits into 618770.

Going ahead to step 1:
When dividing 6 by 12, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 12

Let's proceed to step 2:
12 goes into 61 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 60 from 61, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 12

Going ahead to step 3:
The number 12 fits into 18 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtract 12 from 18 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 12

Moving on to step 4:
The number 12 fits into 67 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 515.0
Subtracting 60 from 67 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 12

Let's proceed to step 5:
If we divide 77 by 12, we get 6 and a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 5156.0
Subtracting 72 from 77 leaves us with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 12

Going ahead to step 6:
50 divided by 12 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 51564.0
Subtracting 48 from 50 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.

On to step 7:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 51564.1
Subtract 12 from 20 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.

On to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 51564.16
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.

Step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 51564.166
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 quotient of the division is 51564.166, and the remainder is 0.0008.
