80940855 ÷ 571 
Let's see how many times 571 fits into 80940855.

On to step 1:
8 divided by 571 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 571

Going ahead to step 2:
The number 571 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 571

Moving on to step 3:
809 divided by 571 is 1 with a remainder of 238.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 571 away from 809, we end up with 238.
Append the next digit (4) from the dividend to 238 and continue with: 2384 / 571

Going ahead to step 4:
If we divide 2384 by 571, we get 4 and a remainder of 100.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 2284 from 2384 and we're left with 100.
Include the next digit (0) from the dividend after 100, then repeat: 1000 / 571

Moving on to step 5:
If we divide 1000 by 571, we get 1 and a remainder of 429.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
If we subtract 571 from 1000, we get 429.
Bring next digit (8) of the dividend behind the 429 and repeat the process: 4298 / 571

Going ahead to step 6:
When dividing 4298 by 571, we get 7 with a remainder of 301.
Record the quotient 7 as the next digit in the result. 
Result so far: 1417.0
If we take 3997 away from 4298, we end up with 301.
Grab the next digit (5) from the dividend, add it to 301, then carry on: 3015 / 571

On to step 7:
The number 571 fits into 3015 5 times, leaving a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 14175.0
Deduct 2855 from 3015 and we're left with 160.
Include the next digit (5) from the dividend after 160, then repeat: 1605 / 571

Going ahead to step 8:
The number 571 fits into 1605 2 times, leaving a remainder of 463.
Write down 2 as next digit of the result. 
Result so far: 141752.0
If we subtract 1142 from 1605, we get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Let's proceed to step 9:
571 goes into 4630 8 times with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 141752.8
The remainder is 62 after subtracting 4568 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
The number 571 fits into 620 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 141752.81
If we take 571 away from 620, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 11:
When dividing 490 by 571, we get 0 with a remainder of 490.
The next digit of our result is 0. 
Result so far: 141752.81
If we take 0 away from 490, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 12:
If we divide 4900 by 571, we get 8 and a remainder of 332.
Put 8 as the next digit of the answer. 
Result so far: 141752.8108
If we subtract 4568 from 4900, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 13:
When dividing 3320 by 571, we get 5 with a remainder of 465.
Record the quotient 5 as the next digit in the result. 
Result so far: 141752.81085
The remainder is 465 after subtracting 2855 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Step 14:
4650 divided by 571 is 8 with a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 141752.810858
If we subtract 4568 from 4650, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 15:
If we divide 820 by 571, we get 1 and a remainder of 249.
Write down 1 as next digit of the result. 
Result so far: 141752.8108581
Subtracting 571 from 820 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 16:
2490 divided by 571 is 4 with a remainder of 206.
The next digit of our result is 4. 
Result so far: 141752.81085814
Deduct 2284 from 2490 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

The final outcome is 141752.81085814, with a leftover of 2.06e-07.
