We divide 80009470 by 66
Let's see how many times 66 fits into 80009470.

On to step 1:
If we divide 8 by 66, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 66

Let's proceed to step 2:
When dividing 80 by 66, we get 1 with 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.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 66

Moving on to step 3:
If we divide 140 by 66, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 132 from 140 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 66

On to step 4:
The number 66 fits into 80 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 121.0
If we take 66 away from 80, we end up with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 66

On to step 5:
66 can be fit into 149 2 times, resulting in a remainder of 17.
The next digit of our result is 2. 
Result so far: 1212.0
If we take 132 away from 149, we end up with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 66

On to step 6:
When dividing 174 by 66, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 12122.0
Subtract 132 from 174 to get 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 66

On to step 7:
When dividing 427 by 66, we get 6 with a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 121226.0
Deduct 396 from 427 and we're left with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 66

Going ahead to step 8:
The number 66 fits into 310 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 1212264.0
Subtract 264 from 310 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
66 can be fit into 460 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 1212264.6
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
The number 66 fits into 640 9 times, leaving a remainder of 46.
The next digit of our result is 9. 
Result so far: 1212264.69
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
If we divide 460 by 66, we get 6 and a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 1212264.696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
66 goes into 640 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 1212264.6969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 13:
66 goes into 460 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 1212264.69696
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
If we divide 640 by 66, we get 9 and a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 1212264.696969
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 15:
460 divided by 66 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 1212264.6969696
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 16:
66 can be fit into 640 9 times, resulting in a remainder of 46.
The next digit of our result is 9. 
Result so far: 1212264.69696969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 1212264.69696969 with a remainder of 4.6e-08.
