We're dividing 80486373 by 771 
Let's see how many times 771 fits into 80486373.

Going ahead to step 1:
The number 771 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 771

On to step 2:
If we divide 80 by 771, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (4) from the dividend, add it to 80, then carry on: 804 / 771

On to step 3:
804 divided by 771 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 771 from 804 leaves us with 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 771

On to step 4:
771 goes into 338 0 times with a remainder of 338.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 338, we get 338.
Fetch the next digit (6) from the dividend, attach it to 338 and continue: 3386 / 771

Moving on to step 5:
If we divide 3386 by 771, we get 4 and a remainder of 302.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we subtract 3084 from 3386, we get 302.
Take the next digit (3) from the dividend and append it to 302, then repeat: 3023 / 771

Let's proceed to step 6:
If we divide 3023 by 771, we get 3 and a remainder of 710.
The next digit of our result is 3. 
Result so far: 1043.0
Subtract 2313 from 3023 to get 710.
Take the next digit (7) from the dividend and append it to 710, then repeat: 7107 / 771

On to step 7:
771 can be fit into 7107 9 times, resulting in a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 10439.0
Deduct 6939 from 7107 and we're left with 168.
Include the next digit (3) from the dividend after 168, then repeat: 1683 / 771

Going ahead to step 8:
1683 divided by 771 is 2 with a remainder of 141.
Put 2 as the next digit of the answer. 
Result so far: 104392.0
If we subtract 1542 from 1683, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 9:
1410 divided by 771 is 1 with a remainder of 639.
Record the quotient 1 as the next digit in the result. 
Result so far: 104392.1
Subtracting 771 from 1410 leaves us with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Going ahead to step 10:
6390 divided by 771 is 8 with a remainder of 222.
Record the quotient 8 as the next digit in the result. 
Result so far: 104392.18
The remainder is 222 after subtracting 6168 from 6390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 11:
If we divide 2220 by 771, we get 2 and a remainder of 678.
Put 2 as the next digit of the answer. 
Result so far: 104392.182
Subtracting 1542 from 2220 leaves us with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Going ahead to step 12:
The number 771 fits into 6780 8 times, leaving a remainder of 612.
Record the quotient 8 as the next digit in the result. 
Result so far: 104392.1828
Deduct 6168 from 6780 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 13:
6120 divided by 771 is 7 with a remainder of 723.
Use 7 as the next digit of our solution. 
Result so far: 104392.18287
Subtract 5397 from 6120 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Step 14:
7230 divided by 771 is 9 with a remainder of 291.
Put 9 as the next digit of the answer. 
Result so far: 104392.182879
If we subtract 6939 from 7230, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 15:
2910 divided by 771 is 3 with a remainder of 597.
Put 3 as the next digit of the answer. 
Result so far: 104392.1828793
The remainder is 597 after subtracting 2313 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Let's proceed to step 16:
The number 771 fits into 5970 7 times, leaving a remainder of 573.
Use 7 as the next digit of our solution. 
Result so far: 104392.18287937
The remainder is 573 after subtracting 5397 from 5970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

The final outcome is 104392.18287937, with a leftover of 5.73e-07.
