670630 ÷ 66 
We're looking to find how many times 66 goes into 670630.

Moving on to step 1:
When dividing 6 by 66, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 66

Moving on to step 2:
The number 66 fits into 67 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 66 from 67 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 66

Advancing to step 3:
66 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 10, we end up with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 66

Moving on to step 4:
106 divided by 66 is 1 with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtracting 66 from 106 leaves us with 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 66

Advancing to step 5:
403 divided by 66 is 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 1016.0
If we subtract 396 from 403, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 66

Step 6:
70 divided by 66 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 10161.0
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 66 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10161.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
66 can be fit into 400 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 10161.06
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
If we divide 40 by 66, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10161.06
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 66, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 10161.0606
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
66 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10161.0606
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
When dividing 400 by 66, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 10161.060606
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
If we divide 40 by 66, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10161.060606
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
66 can be fit into 400 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 10161.06060606
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 10161.06060606 with a balance of 4e-09.
