77342054 ÷ 80 
We're looking to find how many times 80 goes into 77342054.

Step 1:
7 divided by 80 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 80

Moving on to step 2:
If we divide 77 by 80, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (3) of the dividend behind the 77 and repeat the process: 773 / 80

Moving on to step 3:
The number 80 fits into 773 9 times, leaving a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 720 from 773 and we're left with 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 80

On to step 4:
534 divided by 80 is 6 with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 96.0
Subtracting 480 from 534 leaves us with 54.
Take the next digit (2) from the dividend and append it to 54, then repeat: 542 / 80

Step 5:
542 divided by 80 is 6 with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 966.0
If we subtract 480 from 542, we get 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 80

Moving on to step 6:
If we divide 620 by 80, we get 7 and a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 9667.0
The remainder is 60 after subtracting 560 from 620.
Fetch the next digit (5) from the dividend, attach it to 60 and continue: 605 / 80

Going ahead to step 7:
If we divide 605 by 80, we get 7 and a remainder of 45.
The next digit of our result is 7. 
Result so far: 96677.0
Subtracting 560 from 605 leaves us with 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 80

Step 8:
454 divided by 80 is 5 with a remainder of 54.
Record the quotient 5 as the next digit in the result. 
Result so far: 966775.0
Deduct 400 from 454 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
80 can be fit into 540 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 966775.6
If we take 480 away from 540, we end up 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:
If we divide 600 by 80, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 966775.67
Subtract 560 from 600 to 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.

Going ahead to 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: 966775.675
If we take 400 away from 400, we end up 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.

Going ahead to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 966775.675
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.

Going ahead to step 13:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 966775.675
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.

After the division, we end up with 966775.675 and a remainder of 0.0.
