80656607 divided by 66 
We want to figure out the number of times 80656607 can be divided by 66.

Going ahead to step 1:
When dividing 8 by 66, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 66

On to step 2:
The number 66 fits into 80 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 66 from 80, we get 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 66

On to step 3:
146 divided by 66 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 132 from 146 to get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 66

Let's proceed to step 4:
66 goes into 145 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 122.0
Subtract 132 from 145 to get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 66

Advancing to step 5:
66 can be fit into 136 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 1222.0
If we subtract 132 from 136, we get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 66

Advancing to step 6:
66 can be fit into 46 0 times, resulting in a remainder of 46.
The next digit of our result is 0. 
Result so far: 12220.0
The remainder is 46 after subtracting 0 from 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 66

Going ahead to step 7:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 122206.0
Subtracting 396 from 460 leaves us with 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 66

Advancing to step 8:
66 goes into 647 9 times with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 1222069.0
If we subtract 594 from 647, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
If we divide 530 by 66, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1222069.8
If we take 528 away from 530, we end up with 2.
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:
When dividing 20 by 66, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1222069.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1222069.803
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
The number 66 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1222069.803
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
200 divided by 66 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1222069.80303
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1222069.80303
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
If we divide 200 by 66, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1222069.8030303
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 16:
66 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1222069.8030303
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 1222069.8030303 with a remainder of 2e-08.
