We divide 79971841 by 80
We want to divide 79971841 by 80.

Step 1:
80 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 80

Step 2:
79 divided by 80 is 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 80

Moving on to step 3:
799 divided by 80 is 9 with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 720 from 799, we get 79.
Append the next digit (7) from the dividend to 79 and continue with: 797 / 80

Step 4:
The number 80 fits into 797 9 times, leaving a remainder of 77.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we take 720 away from 797, we end up with 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 80

Step 5:
771 divided by 80 is 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 999.0
Deduct 720 from 771 and we're left with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 80

Let's proceed to step 6:
80 can be fit into 518 6 times, resulting in a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 9996.0
Subtract 480 from 518 to get 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 80

Step 7:
When dividing 384 by 80, we get 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 99964.0
The remainder is 64 after subtracting 320 from 384.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 80

On to step 8:
The number 80 fits into 641 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 999648.0
Subtracting 640 from 641 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
80 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 999648.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
If we divide 100 by 80, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 999648.01
If we take 80 away from 100, 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.

Going ahead to step 11:
When dividing 200 by 80, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 999648.012
Subtracting 160 from 200 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.

Moving on to step 12:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 999648.0125
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.

Step 13:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 999648.0125
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.

Going ahead to step 14:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 999648.0125
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.

The quotient of the division is 999648.0125, and the remainder is 0.0.
