We're dividing 66923862 by 80 
We want to divide 66923862 by 80.

Going ahead to step 1:
80 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 80

Step 2:
80 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 80

Moving on to step 3:
If we divide 669 by 80, we get 8 and a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 640 from 669 to get 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 80

Step 4:
292 divided by 80 is 3 with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we subtract 240 from 292, we get 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 80

Moving on to step 5:
80 can be fit into 523 6 times, resulting in a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 836.0
Subtract 480 from 523 to get 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 80

Advancing to step 6:
438 divided by 80 is 5 with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 8365.0
Subtract 400 from 438 to get 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 80

Advancing to step 7:
80 goes into 386 4 times with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 83654.0
If we take 320 away from 386, we end up with 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 80

Advancing to step 8:
80 can be fit into 662 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 836548.0
Subtract 640 from 662 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
220 divided by 80 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 836548.2
Deduct 160 from 220 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
600 divided by 80 is 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 836548.27
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
When dividing 400 by 80, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 836548.275
Subtract 400 from 400 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.

Advancing to step 12:
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: 836548.275
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.

Step 13:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 836548.275
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 836548.275, and the remainder is 0.0.
