We're dividing 80247193 by 66 
We want to figure out the number of times 80247193 can be divided by 66.

Step 1:
When dividing 8 by 66, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 66

Advancing to step 2:
If we divide 80 by 66, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 66 from 80 leaves us with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 66

Let's proceed to step 3:
If we divide 142 by 66, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 132 from 142 and we're left with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 66

On to step 4:
104 divided by 66 is 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Deduct 66 from 104 and we're left with 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 66

Step 5:
387 divided by 66 is 5 with a remainder of 57.
The number 5 becomes the next digit in our result. 
Result so far: 1215.0
Subtract 330 from 387 to get 57.
Bring next digit (1) of the dividend behind the 57 and repeat the process: 571 / 66

Advancing to step 6:
66 goes into 571 8 times with a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 12158.0
If we take 528 away from 571, we end up with 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 66

Moving on to step 7:
66 goes into 439 6 times with a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 121586.0
If we subtract 396 from 439, we get 43.
Include the next digit (3) from the dividend after 43, then repeat: 433 / 66

Let's proceed to step 8:
66 goes into 433 6 times with a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 1215866.0
Subtracting 396 from 433 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
If we divide 370 by 66, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 1215866.5
If we take 330 away from 370, we end up with 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 10:
When dividing 400 by 66, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1215866.56
Subtracting 396 from 400 leaves us 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.

Let's proceed to step 11:
If we divide 40 by 66, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1215866.56
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.

On to step 12:
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: 1215866.5606
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.

On to step 13:
40 divided by 66 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1215866.5606
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
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: 1215866.560606
Subtracting 396 from 400 leaves us 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 15:
66 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1215866.560606
Subtracting 0 from 40 leaves us with 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 16:
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: 1215866.56060606
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.

The final outcome is 1215866.56060606, with a leftover of 4e-09.
