66450629 divided by 8 
We want to divide 66450629 by 8.

Step 1:
The number 8 fits into 6 0 times, leaving 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.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 8

Step 2:
66 divided by 8 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 64 away from 66, we end up with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 8

Going ahead to step 3:
When dividing 24 by 8, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtracting 24 from 24 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 8

If we take 16 away from 22, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 8

Going ahead to step 8:
8 can be fit into 69 8 times, resulting in a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 8306328.0
Subtracting 64 from 69 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
50 divided by 8 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 8306328.6
The remainder is 2 after subtracting 48 from 50.
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 10:
The number 8 fits into 20 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 8306328.62
If we take 16 away from 20, 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.

Step 11:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8306328.625
If we subtract 40 from 40, 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.

Advancing to step 12:
When dividing 0 by 8, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8306328.625
Subtracting 0 from 0 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.

Advancing to step 13:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 8306328.625
Subtracting 0 from 0 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.

In conclusion, the division gives 8306328.625 with a balance of 0.0.
