80580999 ÷ 97 
Let's see how many times 97 fits into 80580999.

Let's proceed to step 1:
97 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 97

Let's proceed to step 2:
97 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Grab the next digit (5) from the dividend, add it to 80, then carry on: 805 / 97

Advancing to step 3:
The number 97 fits into 805 8 times, leaving a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 776 from 805 leaves us with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 97

On to step 4:
If we divide 298 by 97, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtract 291 from 298 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 97

Let's proceed to step 5:
97 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 830.0
Subtract 0 from 70 to get 70.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 97

Step 6:
If we divide 709 by 97, we get 7 and a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 8307.0
Deduct 679 from 709 and we're left with 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 97

Going ahead to step 7:
The number 97 fits into 309 3 times, leaving a remainder of 18.
The next digit of our result is 3. 
Result so far: 83073.0
Subtracting 291 from 309 leaves us with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 97

Going ahead to step 8:
97 can be fit into 189 1 times, resulting in a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 830731.0
Deduct 97 from 189 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 9:
97 can be fit into 920 9 times, resulting in a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 830731.9
If we take 873 away from 920, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 10:
470 divided by 97 is 4 with a remainder of 82.
Put 4 as the next digit of the answer. 
Result so far: 830731.94
If we take 388 away from 470, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 11:
97 can be fit into 820 8 times, resulting in a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 830731.948
Subtracting 776 from 820 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 12:
The number 97 fits into 440 4 times, leaving a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 830731.9484
If we take 388 away from 440, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
The number 97 fits into 520 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 830731.94845
If we subtract 485 from 520, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
350 divided by 97 is 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 830731.948453
Subtract 291 from 350 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 15:
590 divided by 97 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 830731.9484536
Subtracting 582 from 590 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 16:
97 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 830731.9484536
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 830731.9484536 and a remainder of 8e-08.
