670443 ÷ 66 
Let's see how many times 66 fits into 670443.

Going ahead to step 1:
If we divide 6 by 66, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 66

Let's proceed to step 2:
67 divided by 66 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 66 from 67, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 66

On to step 3:
10 divided by 66 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 10 to get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 66

Going ahead to step 4:
When dividing 104 by 66, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 101.0
If we take 66 away from 104, we end up with 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 66

Advancing to step 5:
66 goes into 384 5 times with a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 1015.0
The remainder is 54 after subtracting 330 from 384.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 66

Let's proceed to step 6:
66 can be fit into 543 8 times, resulting in a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 10158.0
Deduct 528 from 543 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
If we divide 150 by 66, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 10158.2
Deduct 132 from 150 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
If we divide 180 by 66, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 10158.22
Subtracting 132 from 180 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 10158.22, with a leftover of 0.048.
