We're dividing 80716173 by 686 
Let's see how many times 686 fits into 80716173.

Advancing to step 1:
If we divide 8 by 686, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 686

Step 2:
80 divided by 686 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 686

On to step 3:
686 can be fit into 807 1 times, resulting in a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 686 from 807 and we're left with 121.
Include the next digit (1) from the dividend after 121, then repeat: 1211 / 686

Advancing to step 4:
686 goes into 1211 1 times with a remainder of 525.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 686 from 1211, we get 525.
Bring next digit (6) of the dividend behind the 525 and repeat the process: 5256 / 686

On to step 5:
686 goes into 5256 7 times with a remainder of 454.
Write down 7 as next digit of the result. 
Result so far: 117.0
The remainder is 454 after subtracting 4802 from 5256.
Grab the next digit (1) from the dividend, add it to 454, then carry on: 4541 / 686

Advancing to step 6:
When dividing 4541 by 686, we get 6 with a remainder of 425.
Use 6 as the next digit of our solution. 
Result so far: 1176.0
If we take 4116 away from 4541, we end up with 425.
Fetch the next digit (7) from the dividend, attach it to 425 and continue: 4257 / 686

Going ahead to step 7:
4257 divided by 686 is 6 with a remainder of 141.
Use 6 as the next digit of our solution. 
Result so far: 11766.0
Deduct 4116 from 4257 and we're left with 141.
Append the next digit (3) from the dividend to 141 and continue with: 1413 / 686

On to step 8:
1413 divided by 686 is 2 with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 117662.0
If we take 1372 away from 1413, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
The number 686 fits into 410 0 times, leaving a remainder of 410.
Write down 0 as next digit of the result. 
Result so far: 117662.0
If we take 0 away from 410, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 10:
When dividing 4100 by 686, we get 5 with a remainder of 670.
Put 5 as the next digit of the answer. 
Result so far: 117662.05
The remainder is 670 after subtracting 3430 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 11:
If we divide 6700 by 686, we get 9 and a remainder of 526.
The next digit of our result is 9. 
Result so far: 117662.059
If we take 6174 away from 6700, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Let's proceed to step 12:
5260 divided by 686 is 7 with a remainder of 458.
Use 7 as the next digit of our solution. 
Result so far: 117662.0597
Subtracting 4802 from 5260 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 13:
When dividing 4580 by 686, we get 6 with a remainder of 464.
Use 6 as the next digit of our solution. 
Result so far: 117662.05976
Subtract 4116 from 4580 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 14:
If we divide 4640 by 686, we get 6 and a remainder of 524.
Write down 6 as next digit of the result. 
Result so far: 117662.059766
The remainder is 524 after subtracting 4116 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

After the division, we end up with 117662.059766 and a remainder of 5.24e-05.
