Let's see how many times 686 fits into 87795073.

Advancing to step 1:
8 divided by 686 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 686

Going ahead to step 2:
87 divided by 686 is 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 686

Going ahead to step 3:
When dividing 877 by 686, we get 1 with a remainder of 191.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 191 after subtracting 686 from 877.
Bring next digit (9) of the dividend behind the 191 and repeat the process: 1919 / 686

Moving on to step 4:
When dividing 1919 by 686, we get 2 with a remainder of 547.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1372 from 1919, we get 547.
Include the next digit (5) from the dividend after 547, then repeat: 5475 / 686

Moving on to step 5:
When dividing 5475 by 686, we get 7 with a remainder of 673.
Put 7 as the next digit of the answer. 
Result so far: 127.0
The remainder is 673 after subtracting 4802 from 5475.
Grab the next digit (0) from the dividend, add it to 673, then carry on: 6730 / 686

Advancing to step 6:
The number 686 fits into 6730 9 times, leaving a remainder of 556.
The next digit of our result is 9. 
Result so far: 1279.0
If we subtract 6174 from 6730, we get 556.
Fetch the next digit (7) from the dividend, attach it to 556 and continue: 5567 / 686

On to step 7:
686 goes into 5567 8 times with a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 12798.0
If we take 5488 away from 5567, we end up with 79.
Grab the next digit (3) from the dividend, add it to 79, then carry on: 793 / 686

Advancing to step 8:
686 goes into 793 1 times with a remainder of 107.
Record the quotient 1 as the next digit in the result. 
Result so far: 127981.0
Subtracting 686 from 793 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 9:
686 goes into 1070 1 times with a remainder of 384.
Put 1 as the next digit of the answer. 
Result so far: 127981.1
Subtract 686 from 1070 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 10:
3840 divided by 686 is 5 with a remainder of 410.
Put 5 as the next digit of the answer. 
Result so far: 127981.15
If we take 3430 away from 3840, 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.

Advancing to step 11:
The number 686 fits into 4100 5 times, leaving a remainder of 670.
Write down 5 as next digit of the result. 
Result so far: 127981.155
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.

The final outcome is 127981.155, with a leftover of 0.067.
