We're dividing 42666947 by 80 
We want to figure out the number of times 42666947 can be divided by 80.

On to step 1:
4 divided by 80 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 80

Going ahead to step 2:
80 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 80

Let's proceed to step 3:
80 goes into 426 5 times with a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 400 away from 426, we end up with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 80

Moving on to step 4:
80 goes into 266 3 times with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtracting 240 from 266 leaves us with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 80

Moving on to step 5:
266 divided by 80 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 533.0
If we subtract 240 from 266, we get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 80

Let's proceed to step 6:
When dividing 269 by 80, we get 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 5333.0
If we take 240 away from 269, we end up with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 80

Let's proceed to step 7:
80 can be fit into 294 3 times, resulting in a remainder of 54.
The next digit of our result is 3. 
Result so far: 53333.0
If we take 240 away from 294, we end up with 54.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 80

Step 8:
547 divided by 80 is 6 with a remainder of 67.
The number 6 becomes the next digit in our result. 
Result so far: 533336.0
If we subtract 480 from 547, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 9:
If we divide 670 by 80, we get 8 and a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 533336.8
Subtracting 640 from 670 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
When dividing 300 by 80, we get 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 533336.83
If we subtract 240 from 300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
80 can be fit into 600 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 533336.837
Deduct 560 from 600 and we're left 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.

Step 12:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 533336.8375
Subtracting 400 from 400 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.

On to step 13:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 533336.8375
Subtract 0 from 0 to 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.

On to step 14:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 533336.8375
If we subtract 0 from 0, 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.

Our division results in 533336.8375 with a remaining 0.0.
