Let's divide 669443 by 12
We want to figure out the number of times 669443 can be divided by 12.

Moving on to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 12

On to step 2:
The number 12 fits into 66 5 times, leaving a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 6 after subtracting 60 from 66.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 12

Going ahead to step 3:
If we divide 69 by 12, we get 5 and a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we take 60 away from 69, we end up with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 12

On to step 4:
12 can be fit into 94 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 557.0
If we take 84 away from 94, we end up with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 12

Step 5:
If we divide 104 by 12, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 5578.0
Subtract 96 from 104 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 12

On to step 6:
The number 12 fits into 83 6 times, leaving a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 55786.0
Subtracting 72 from 83 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
12 goes into 110 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 55786.9
The remainder is 2 after subtracting 108 from 110.
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 8:
12 goes into 20 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 55786.91
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.

Step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 55786.916
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.

Advancing to step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 55786.9166
Deduct 72 from 80 and we're left 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 55786.9166, and the remainder is 8e-05.
