97901244 divided by 80 
We want to figure out the number of times 97901244 can be divided by 80.

Going ahead to step 1:
If we divide 9 by 80, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 80

Let's proceed to step 2:
The number 80 fits into 97 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 80 away from 97, we end up with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 80

Let's proceed to step 3:
If we divide 179 by 80, we get 2 and a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 19 after subtracting 160 from 179.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 80

Let's proceed to step 4:
80 can be fit into 190 2 times, resulting in a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we subtract 160 from 190, we get 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 80

Moving on to step 5:
If we divide 301 by 80, we get 3 and a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 1223.0
Deduct 240 from 301 and we're left with 61.
Include the next digit (2) from the dividend after 61, then repeat: 612 / 80

Going ahead to step 6:
80 can be fit into 612 7 times, resulting in a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 12237.0
The remainder is 52 after subtracting 560 from 612.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 80

Going ahead to step 7:
The number 80 fits into 524 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 122376.0
Subtract 480 from 524 to get 44.
Fetch the next digit (4) from the dividend, attach it to 44 and continue: 444 / 80

On to step 8:
80 goes into 444 5 times with a remainder of 44.
The next digit of our result is 5. 
Result so far: 1223765.0
Subtract 400 from 444 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
440 divided by 80 is 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 1223765.5
The remainder is 40 after subtracting 400 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1223765.55
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.

The quotient of the division is 1223765.55, and the remainder is 0.0.
