We divide 644176 by 66
We're looking to find how many times 66 goes into 644176.

On to step 1:
66 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 66

Moving on to step 2:
66 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 66

Let's proceed to step 3:
When dividing 644 by 66, we get 9 with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 594 away from 644, we end up with 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 66

Step 4:
66 goes into 501 7 times with a remainder of 39.
The next digit of our result is 7. 
Result so far: 97.0
If we subtract 462 from 501, we get 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 66

On to step 5:
The number 66 fits into 397 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 976.0
If we take 396 away from 397, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 66

Let's proceed to step 6:
16 divided by 66 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 9760.0
If we take 0 away from 16, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
The number 66 fits into 160 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 9760.2
Deduct 132 from 160 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
66 can be fit into 280 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 9760.24
Subtracting 264 from 280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 66, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 9760.242
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
280 divided by 66 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 9760.2424
Deduct 264 from 280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
160 divided by 66 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 9760.24242
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
66 goes into 280 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 9760.242424
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
160 divided by 66 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 9760.2424242
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
When dividing 280 by 66, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 9760.24242424
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 9760.24242424, and the remainder is 1.6e-08.
