97542758 divided by 80 
Let's see how many times 80 fits into 97542758.

Step 1:
9 divided by 80 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 80

Step 2:
When dividing 97 by 80, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 80 from 97, we get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 80

On to step 3:
80 goes into 175 2 times with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 160 from 175 leaves us with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 80

Going ahead to step 4:
80 goes into 154 1 times with a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Subtracting 80 from 154 leaves us with 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 80

Moving on to step 5:
The number 80 fits into 742 9 times, leaving a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 1219.0
Deduct 720 from 742 and we're left with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 80

Moving on to step 6:
80 can be fit into 227 2 times, resulting in a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 12192.0
The remainder is 67 after subtracting 160 from 227.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 80

Moving on to step 7:
80 goes into 675 8 times with a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 121928.0
The remainder is 35 after subtracting 640 from 675.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 80

Advancing to step 8:
If we divide 358 by 80, we get 4 and a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 1219284.0
The remainder is 38 after subtracting 320 from 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
The number 80 fits into 380 4 times, leaving a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 1219284.4
If we subtract 320 from 380, 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 10:
80 goes into 600 7 times with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 1219284.47
Subtracting 560 from 600 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 11:
When dividing 400 by 80, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1219284.475
The remainder is 0 after subtracting 400 from 400.
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:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1219284.475
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.

Advancing to step 13:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1219284.475
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 final outcome is 1219284.475, with a leftover of 0.0.
